Question

A rectangular garden has a width of 10 feet and a length of 14 feet. A cement

walkway is added around the outside of the garden. The area of the garden and the
walkway together are 252 square feet. What is the width of the walkway?

Answer 1

Total area=252 sq ft
Area of garden=10*14= 140 sq ft
Area of walkway=252-140= 112 sq ft
Walkway is around the garden, therefore its length is 24 ft (=10+14)
Walkway width=112/24= 4.7 ft
