Question

Yael used to have a square garage with 222 ft2 of floor space. She recently built an addition to it. The garage is still a 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

Answer 1

Answer:

• The length of one side of the garage originally is approximately 14.9 ft

,

• The length of one side of the garage now​ is approximately 18.3 ft

Explanation:

Old garage = 222 sq. ft

New garage has 50% more floor space.

50% of 222 = 111

Therefore, the new garage is (222 + 111) sq. ft = 333 sq. ft

Since the garage is square,

one side of the old garage is:

$\sqrt[]{222}=14.9\text{ ft}$

One side of the new garage is:

$\sqrt[]{333}=18.3\text{ ft}$
