Question

the length of a rectangle is 3 more than the width find the length of the rectangle if the perimeter is 98 inches

 

Answer 1

 

Let  w = width

Let w + 3 = length

 

Perimeter = 2L +2W       

    98 = 2(w + 3) + 2w

    98 = 2w + 6 + 2w

    98 = 4w + 6

    92 = 4w

    w = 92/4

    w = 23

 

Width is 23 inches

Length is 3 more ... Length is 26
