What is the area of a square if one side is 30 cm long?

Wel, since it is a square, all sides are equal to one another.  So they are all 30 cm long.  And Area=length*width.  So 30 times 30 is 900. The answer is 900cm^2

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
