What's a mural with an area of 18m2

Assuming that the mural is a perfect square, therefore the formula for area is simply:

A = s^2

where A is area and s is the measure of the sides

Therefore from the formula, we can calculate the side lengths of the mural, s:

18 m^2 = s^2

s = sqrt (18 m^2)

s = 4.24 m

So the mural has a dimensions of 4.24 m by 4.24 m
