48 : (17 - 15)³ - 5 = 48 : 2³ - 5 =
= 48 : 8 - 5 = 6 - 5 = <u>1</u>
First, find the length of one side of a square:
Area = side²
11 = s²
s = √(11) cm
Since there are 8 squares on each side, multiply the length of one square by 8 to get the length of 8 squares.
√(11) * 8 = 8√(11) ≈16.5 cm
Hope this helps!
