How do you find out the height of a rectangle if you know the width and length?
multiply them
How do you find the area from the perimeter of a rectangle?
If the only information that you have is ... A) the figure is a rectangle, and B) the perimeter ... then you cannot calculate the area. The area of a rectangle is the length multiplied by the height., The perimeter is twice the length plus twice the height. So, a rectangle with a length of 9 units and a height of 1 unit will have a perimeter of 20 units and an area of 9 square units. Another rectangle with a length of 6 units and a height of 4 units will also have a perimeter of 20 units, but it will have an area of 24 square units. To be able to calculate the area from the perimeter you need to know one of two additional things - either one of the measurements, or the ratio of the height to the length.+++To summarise, you can, IF you know the ratio as mentioned. Then apply that to half the perimeter to find the length and breadth.
How do I find the area of a rectangle if I only have the length?
You cannot find the area of a rectangle if you only know its length. You need to know its width too. Then you multiply its length by its width.
How do you find the length and breadth if area is known for a rectangle?
If you do not know the length or breadth of a rectangle, you cannot know the area. If you do not know the area of a rectangle, you cannot know the length and breadth. To know the length and breadth of a rectangle, you have to know some other contributing factor in the equation. If you don't, measure it!
How do you find the square footage of a 9' by 9' room?
Area of rectangle = Length x Breadth = 9x 9= 81sq feet Acc. to me a room has three dimensions length, breadth and height. If you know the area of the woom and length and breadth you can find height.
How do you find the width of a rectangle if you know its length and area?
Area of rectangle divided by its length = width of rectangle
What do you have to know to find the area of a parallelogram?
divide the parralelogram into three sections--a rectangle and two triangles and find the area of each (triangle is 1/2 base x height) (rectangle is length times width
How do you find the volume of a rectangular prism if you know the base and height?
A rectangle volume is length X width X height = volume The fact its a prism is irrelevant as long as it is a box shape.
How do you find the length of a rectangle if the width is 5?
You would also need to know the area of rectangle, along with the width in order to determine the length of the rectangle.
How do you find the width of a rectangle when you know its area and length?
You divide area by length or area/length.
How do you find the area of a rectangle with 3 angles given?
A rectangle is, by definition, a parallelogram with four equal angles, all of which equal 90 degrees. If you only know three angles in a rectangle, something is wrong. In order to find the area of a rectangle, you must know its height and length. The area is then found by multiplying these two values together.
What formula do you use to find the height of a rectangle while knowing the area and volume?
The volume of the rectangle is of no use to you, since the volume of every rectangleis zero. What you need to know is the rectangle's area and length.You're supposed to know that the area is the product of (length) times (height).So if you know the area and one of the dimensions, you can use that formula tofind the other dimension.
