Question

7. A rectangle has a length that is 2 cm less than 3 times the width. The perimeter of the

rectangle is 34 cm. Determine the dimensions of the rectangle.

Answer 1

width=4.75cm

length=12.25cm

Explanation:

let the width of the rectangle=x

the length=3x-2

Given that perimeter=34cm,

2(x)+2(3x-2)=34

2x+6x-4=34

8x-4=34

8x=38

x=38/8=4.75cm

Therefore,

width=4.75cm

length=12.25cm
