Question

A rectangular garden has a width of 5 feet and a length of 10 feet. If an equal amount is added to both the width and the length, the area is increased to 126 square feet. What is this amount?

Answer 1

5 x 10 = 50 square feet

Add 4 to each number and then multiply and you'll get 126

9 x 14 = 126 square feet

Answer 2

well, what we need to know is what the height is, so we know we have a width of 5 ft. , a length of 10 ft. , and we know the area aka volume is 126 ft2. (squared ft.) so we multiply 5ft. by 10ft. which gets us 50 ft. But we need to add on 126 squared ft.) that gives us 176 ft2. so the amount is 176 ft2! Hope this helped you :)
