Yossi used to have a square garage with 248ft2.He 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? What was the percent increase in the length of one​ side?



Answer :

The length of one side of the garage originally is 15.7 feet.

The length of one side of the garage now is 19.3 feet.

The percentage increase will be 18.65%.

How to calculate the value?

It should be noted that the area = side × side

1. There's a 50% increment. This will be:

= New area = 248 × (100% + 50%)

= 248 × 1.5

= 372ft²

Therefore, the sides or length will be:

= ✓372

= 19.3 feet

2. Length of original garage will be:

= ✓248

= 15.7 feet

3. The percentage increase will be:

= (19.3 - 15.7)/19.3 × 100

= 18.65%
