Area = 20*10 = 200 square units
yeah
A parallelogram is just a rectangle leaned to one side
Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b
One dimension of a rectangle is its length, which is the longer side of the rectangle. The other dimension is its width, which is the shorter side. Together, these dimensions define the size and shape of the rectangle.
To find the area of a rectangle, you multiply the length by the width (one side by a different side) Or you could count how many centimeter squares make up the rectangle
yeah
300 mm2
If the perimiter is 20 and one side is [[length]] then the other side is (10 - [[length]]). So the area is: [[length]] x (10 - [[length]]) square metres.
To determine the other side of a larger rectangle when given one side, you typically need the area or the aspect ratio of the rectangle. If you have the area, you can divide it by the known side to find the other side. Alternatively, if the aspect ratio is provided, you can use it to calculate the other dimension. Without specific values or additional information, it's not possible to provide a precise answer.
Look at it this way, suppose x is one side of the rectangle and y is the other. Then the area of the rectangle would be xy. Now if you double each side of the originial rectangle you would have each side as 2x and 2y. So the area of the new rectangle would be 2x*2y or 4xy. As you can see the new area is 4 times larger than the original.
Divide the area by the known side.
One side 8 long, other side 3 long.

Since the area of a rectangle is equal to the product of its two sides, then 4x - 3 is one factor of the product 12x^2 + 19x - 21 which represents the area. So the other factor is 3x + 7. Check: Or the given side could be 4x + 3 and the other side is 3x - 7, in order to obtain the area 12x^2 - 19x - 21.

Area = length x width. You have one of the sides; to get the other side, use the Pythagorean Theorem. Then multiply the two sides.
