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!
