Question

If the area of a square is 7.29 square yards, what is the length of one of the sides?

Answer 1

Answer:

2.7

Step-by-step explanation:

Since the shape is a square, just square root its area to get its side's sides.

Square root 7.29:

2^2 is 4, and 3^2 is 9, so we know that the answer is somewhere between 2 and 3

Let's try 2.5:

2.5^2 = 2.5*2.5 = 6.25, not quite

Let's try 2.6:

2.6^2 = 2.6*2.6 = 6.76, still a bit short

Let's try 2.7:

2.7^2 = 2.7*2.7 = 7.29, We have 7.29, so 2.7 is the answer!
