Explanation for Question 7 From the Math (Calc) Section on the 2020 October Sat
So question seven tells us about a square and it says that the area 2 is 36 square inches. So I put a 36 in the middle of here, 3 then ask what is the length in inches of each side of the square? 4 And so we need to know that that equation for area of a square 5 is the sideline squared. And we know that the area 36, 6 so we can ask ourselves what is the square root of 36? 7 And we know that six is the square root. 8 So our side length must be B six.
