Question

If a rectangle's length is 7 more than 4 times the width and the perimeter is 54 what are the dimensions of the rectangle?

Answer 1

let w = width of the rectangle
4w+7 = length of the rectangle

perimeter = 2 lengths + 2 widths

2w + 2(4w+7) = 54
2w + 8w + 14 = 54
10w = 40
w = 4
4w+7 = 23

dimensions of rectangle:
width = 4
length = 23 hope this helps
