Question

The length of a rectangle is 3 centimeters less than twice its width. The perimeter of the rectangle is 48 cm. What are the dimensions of the rectangle?
A)length = 15 cm; width = 9 cm
(B)length = 11 cm; width = 7 cm
(C)length = 12 cm; width = 12 cm
(D)length = 14 cm; width = 10 cm

Answer 1

answer is a)
l = 2b -3
2b +2l = 48
solving we get
l = 15
b = 9

Answer 2

Let the length of the rectangle be l and width be w
Since it is given that the length is 3cm less than twice the width we have
l=2w-3
But
Perimeter P=2(w+l)
48=2(w+l)
Dividing both sides by 2 we get
24=l+w
28=2w-3+w
solving this we will get the value of w.
Substituting in
l=2w-3 we can find l
