The ratio width to length of a rectangle is 2:5 if the perimeter of the rectangle is 100 find the width and length of the given rectangle

width (w) = 2x

length (l) = 5x

Perimeter = 2l+2w = 100 (divide each side of the equation by 2)

P = l+w=50

5x+2x = 50

7x=50

x≈7.14

length = 5x = 5 (7.14) ≈ 35.71

Answer:

The length of this rectangle is about 35.71 units long.
