Question

The length of a rectangle is twice its width..its area is 72cm.find the length and the width of the rectangle

Answer 1

Answer:

Let the breadth of a rectangle be x cm.

So, the length be 2x cm.

Area of the rectangle given= 72 cm

length × breadth =72 cm

x×2x= 72

2x^2=72

x^2=72/2

x^2=36

x=6 cm

breadth of the rectangle =6cm

length of the rectangle = 6×2=12 cm
