Let h and w equal the dimensions of the rectangle and A equal its area
2h + 2w = 30
The perimeter of the rectangle is the sum of its sides, two widths and two heights
h*w = A
The formula for the area of a rectangle
We have two equations but three unknown variables. Without more information about this rectangle, it is impossible to solve for the area from the perimeter alone unless this rectangle was specified as being a square (which gives us a third equation, b = h )
The rectangle has dimensions of [ 12 x 3 ].
the perimeter of a rectangle with two 5cm squares will be 30cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

30cm
the perimeter of a rectangle with two 5cm squares will be 30cm
30cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
Area : 44cm² Perimeter : 30cm
if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm
You an calculate the area of a rectangle by multiplying length x width.
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
The perimeter of the rectangle is the sum of its 4 sides.
