what is the width of the rectangle?


7 cm


9 cm

17 cm

Verified Answer :

Length =x
width=x-8
Perimeter of a rectangle=2(length) + 2(width)

We can suggest this equation:
2x+2(x-8)=52
2x+2x-16=52
4x=52+16
4x=68
x=68/4
x=17

length=x=17
width=x-8=17-8=9

Answer: the width of this rectangle is :   9 cm
