One side of the rectangle is 2.5 times larger than the other.

One side of the rectangle is 2.5 times larger than the other. The area of a rectangle is equal to the area of a square with a side of 6 cm. What are the sides of the rectangle?

S of a square, like a rectangle, is equal to 36 square centimeters.

The width and length of the rectangle are referred to as x and 2.5x. therefore, the area can be written like this:

S = x * 2.5x;

2.5 x2 = 36 cm2

x2 = 36: 2.5 = 16 cm.

x = 4, so the width is 4, and the length is 4 * 2.25 = 9 years.
