Question

Find the area of a square that is 0.21m on a side. (Round the area to the nearest hundredth)

Answer 1

The area of a rectangle is always base * height, in this case, for a square the base and height are equal so, it is equal to the side^2

Answer 2

i have these choices: 0.04m^2
0.42m^2
0.84.m^2

Answer 3

A = s^2
A = (0.21 m)^2
A = 0.21 * 0.21 m^2

Answer 4

so will it be 0.42m^2?

Answer 5

Do you have a calculator?
0.21 * 0.21 is not the same as 0.21 + 0.21

Answer 6

that would equal to 0.0441 if you multiply

Answer 7

Correct.
Since you are asked to round to the nearest 100th, the answer is 0.04 m^2
