Question

If the width is 3 less than the length of a rectangle, and it’s perimeter is 98 inches, what are the dimensions of the rectangle?

Answer 1

Answer: 26 inches and 23 inches

Explanation:

a=width

b=length

Perimeter=98=2*a+2*b

2*a+2*b=98. Equation 1

a=b-3. Equation 2

Using equation 1 we have:

2*(b-3)+2*b=98

2*b-6+2*b=98

4*b=98+6

b=104/4

b=26 inches= length

So a=b-3= 26-3=23 inches= width
