Question

square room in Amber's home has an area of 128 square feet. Which is the best estimate of one side of the room? *

Answer 1

30 since you said square room and a square has 4 equal sides. The actual number is 32

Answer 2

We are given that the shape of the room is a square .

So formula for area of a square is given by:

Area = side * side = side²

Now in the question we are given that the area of the square room is 128 square feet and we have to estimate the side of this square.

So plugging the value of area in the formula given above to find the side,

128 = side²

taking square root on both sides

$\sqrt{128} =side$

side = 11.3137 feet

Answer : The best estimate of one side of the room is 11.3137 feet.
