Solving area and perimeter

Question

A rectangular garden bed is 9 yards wide. It sis 6 times as long as it is wide. Sal walks around the perimeter of the garden bed. How many yards does Sal walks?

Answer 1

Since the garden bed is 6 times as long as it is wide, we can multiply the width

by 6 to determine the length: 9 • 6 = 54 yards

The length is 54 yards.

The perimeter of the garden bed is the distance walked. Here this would be:

perimeter = 2 • length + 2 • width

perimeter = 2 • 54 + 2 • 9

perimeter = 108 + 19

perimeter = 127 yards

Sal walked 127 yards around the garden bed.
