Question

Yossi used to have a square garage with 334ft^2 of floor space. He recently built an addition to it. The garage is still square, but now it has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the precent increase in the length on one side?

​

Answer 1

Increase in the length of one side = 3.8 ft

Explanation:

Yossi has garage whose area is 280 ft²

After rebuilt their is increment in area by 50%

New Area = 280 × 150% = 420 ft²

Also we know that Area of Square = (Length) × (Length)

⇒ Length of Newly built garage = √420 = 20.5 ft

and Length of Originally garage = √280 = 16.7 ft

⇒ Increase in the length of one side = 20.5 - 16.7 = 3.8 ft
