One side of a rectangle is 2 cm longer than a second side. If the area is 35  cm 2 , find the dimensions of the rectangle.

To determine

To find:

The dimensions of the rectangle.

Explanation

Postulate:

The area A of a rectangle whose base has length b and whose altitude has length h is given by A=bh

Calculation:

Given:

Area of the rectangle = 35 cm2

Suppose the dimensions of rectangle are x, y. It is stated that one side of the rectangle is two times longer than a second side. So length of sides of rectangle can be taken as x,x+2.

Sketch the rectangle as follows:

The area of the rectangle A=bh

b=x,h=x+2
