marishachu [46]
For a square, the area is the square of the side length (length x width = area, but in a square length = width). That means the side length is the square root of the area.

In this case the side length is the square root of 121, which is 11. Answer is C.

80% is 125% of what number?
Korvikt [17]

Answer:

125 is 80% of 156.25

Working out percentages

We have, 80% × x = 125

or,  

<u>80 </u>

100

x = 125

Multiplying both sides by 100 and dividing both sides by 80,

we have x = 125 ×  

<u>100 </u>

80

x = 156.25

If you are using a calculator, simply enter 125×100÷80, which will give you the answer.

Hope This Helps!    Have A Nice Day!!
