Question

the width of a rectangle is 3 feet less than its length. The perimeter of the rectangle is 98 feet. Find the dimensions of the rectangle.

Answer 1

suppose Length of a rectangle= x feet

Width of a rectangle= (x-3) feet

Perimeter of a rectangle = 2(Length+width)

                         98=2(x+x-3)

divide by 2,

                          49= 2x-3

                          52=2x

                          x=26,

x-3=26-3=23

 

length= 26 feet, width =23 feet
