Question

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

Answer 1

`16\:\mathrm{ft^2}`

Explanation:

Trish's initial garden had an area of
`8\cdot8=64\:\mathrm{ft^2}`. After expanding her garden to be 10 feet by 8 feet, the garden has an area of
`8\cdot 10=80 \:\mathrm{ft^2}`. Therefore, the garden was expanded by
`80-64=\boxed{16\:\mathrm{ft^2}}`
