Question

The surface area of the moon is 37,932,330km squared. Calculate the side length of a square with the same area.

Answer 1

First, you need to know that formula for the area of a square with the information given - length ^2
Since you know that the area is length^2then you would plug in the information given for the length which would be 37,932,330 then you take the square root of that because the opposite of ^2 would be the square root of the number. You would then get 6160km which is equal to three other figures but is also going to be your answer. 6160Km

Answer 2

area of a square = length²
length² = 37 932 330
length = √37 932 330
= 6160 km (to three signifcant figures)

The side length of a square with the same area would then be 6160 km.
