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

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

To find the area of a square with a given perimeter, we need to remember that the perimeter of a square is equal to four times the length of one side. In this case, we know that the perimeter is 76 millimeters.

Step 1: Divide the perimeter by 4 to find the length of one side.
76 millimeters ÷ 4 = 19 millimeters.

Step 2: Since all sides of a square are equal, the length of one side is 19 millimeters.

Step 3: To find the area of the square, we multiply the length of one side by itself.
19 millimeters × 19 millimeters = 361 square millimeters.

Therefore, the area of the square with a perimeter of 76 millimeters is 361 square millimeters.
