WHAT'S THE AREA OF A SQUARE WITH A PERIMETER OF 76 MILLIMETERS?

2 answers

The perimeter of a square can be found by adding all the sides.

All of the 4 sides are equal, so 4*s = p

s = ?

The area can be found by s^2. a = ?
P = 4*a = 76 mm
A = a*a = ??

as 76/4 = 19, a = 19
as a = 19, A = 361

-> A = 361 mm²
