How can you find the area of a parallelogram if you only know the side lengths?

The area of a parallelogram is equal to base times height. You can find the maximum area of a parallelogram by multiplying the length of a short side by the length of a long side. (This would be the area if the parallelogram were a rectangle.)
You cannot know the area of a parallelogram if all you know is the length of the sides; you can only know the maximumpossible area. Imagine you slant the parallelogram a lot. The area will decrease, but the side lengths will stay the same.

How can coordinates help you to find the area of figures on the coordinate plane?
Once you know the coordinates, you can use the distance formula to find the lengths of the sides, then using that, you can find the area.
Can a triangle have the same perimeter and area as a parallelogram?
I don't know about the relation in the perimeters of a triangle and a parallelogram but if a triangle is on the same base on which the parallelogram is and the triangle is between the same parallel lines of the parallelogram, then the area of the triangle will be half the area of the parallelogram. That is, area of a triangle = 1/2 area of a parallelogram if the triangle is on the same base and between the same parallel lines.
How do you find the base area of a rectangular prism?
If you know the Volume and the Height of the prism, then you can divide the volume by the height to get the base area. B=V/H If you know the side lengths of the base then you could simply multiply them together to get the base area.
The quadrilateral above has four sides whose lengths are represented by A B C and D If you wanted to calculate the area of the quadrilateral which of the lengths must you know to make the calculation?

How do you find which triangle if you know the lengths of the sides of a triangle whether it is isosceles or equilateral or scalene?
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
How do you find the area of a parallelogram if an angle is 30 degrees and the height is unknown?
You can if you know the lengths of the two pairs of sides. Thanks to the fact that sin(30) = 0.5, the height of the parallelogram is half the length of the sloping side.
How do you find the area of a parallelogram without its height?
You would need to know its side lengths and angles and then you can compute height
If two parallelograms are similar what do you know about the ratios of the two side lengths within one parallelograms and the ratios of the correspondingside lengths in the other parallelogram?
If and when two parallelograms are similar, you know that the ratio of two side lengths within one parallelogram will describe the relationship between the corresponding side lengths in a similar parallelogram. If and when two parallelograms are similar, you know that the ratio of corresponding side lengths in the other parallelogram will give you the scale factor that relates each side length in one parallelogram to the corresponding side length in a similar parallelogram.
How do you calculate the height of a parallelogram?
That depends upon what you know about the parallelogram. If you know the area and base length, then: area of parallelogram = base X height height =area / base If you know the lengths of the two pairs of parallel sides and the angles, then trigonometry can be used. If the height is required between one pair of sides, then: height = other_side_length / sine(angle_between_sides)
How do you find the area of a parallelogram if i don't know the height?
It depends on what information you DO have.
What do you need to know to find the area of a parallelogram?
Its length and its perpendicular height Area = length*height
How do you find the area of a parallelogran with different measures on its sides?
You cannot. You need to know, or be able to calculate, its [perpendicular] height and information about the side lengths is not enough to determine that.A parallelogram can be flexed into a rectangle (when its area is maximised) to a long thin shape with area tending to zero.
How do you find the area and perimeter if the figure does not have equal sides?
For the perimeter, you just go round the shape, adding the lengths of each side as you go along. There may or may not be simple formulae of the area for a shape with unequal sides. If all you know is the [different] side lengths then only a triangle has a relatively simple formula for its area. If you also know that some of the sides are parallel, then you can find the area of a rectangle. Then, if you also know the perpendicular distance between the parallel sides, you can do a parallelogram. If, in addition you know which sides are parallel, a trapezium. And so on.
Which formula should you use to find the area of a parallelogram?
There is no exact formula to find the area of a parallelogram * * * * * It all depends on what information you do have. If you know the base length, B, and the vertical height, H, then the area is B*H square units. If you don't know H but know an angle then some trigonometry will enable you to find H.
Is it true that you can't find the perimeter if you don't know the area?
Not exactly. If I know the side lengths, I can still find the perimeter
How do you find the perimeter if you don't know the area?
You can find the permeter if you know the length of the sides. You need to add the lengths of all the sides together.
How do you find the base of a parallelogram?
If you know its area then divide its height into the area which will give the length of the base of the parallelogram
