Question

John decided to expand his backyard deck. The dimensions of the rectangular deck are 25 feet by 30 feet. His new deck will be 50 feet by 600 feet. How much bigger will the new deck be?

Answer 1

`29,250` sq. ft. larger or `40` times larger.

Explanation:

Current size: `25'xx30' =750 sq.ft.`

New size: `50'xx600' = 30,000 sq. ft.`

Difference in size: `30,000 sq.ft. - 750 sq.ft= 29,250 sq.ft.`

As a ratio: `(30,000 sq.ft.)/(750 sq.ft.) = 40`
