Question

The width of a rectangle is 10cm less than its lenght and its perimeter is 60cm find its the width of the rectangle

Answer 1

Answer:

10 cm

Step-by-step explanation:

Let length be x cm. Thus, width = (x-10) cm

Perimeter= 2 (x + x-10)= 60 cm

x + x-10= 30 cm

2x= 40 cm

x= 20 cm

Thus, width= (x-10) cm = (20-10) cm = 10 cm
