Question

Trish had a square garden with side lengths of 8 feet. She extended her garden to 10 feet, By how many square feet did she expand the area of her garden?

Answer 1

This is a subtraction problem where we are looking for the difference between an 8x8 plot and a 10x10

10^2-8^2

100-64= 36

The garden was expanded by 26 square feet
