The perimeter of a square is 48 centimeters. what is its area?

The area is 144 units.

area is length × width

squares have an equal lenght and width, and 4 sides. if a square's perimeter is 48, we need to divide that by 4 to get the size of each side.

48 ÷ 4 = 12

each side is 12 units. to get the area, we need to mutliple length × width, in this case 12 × 12, which equals 144 units.

x = 9/4.

step-by-step explanation:

x/3 + 1/2 = 5/4

multiply through   by the lcd of   2,3 and 4 which is 12.

4x + 6 = 15

4x = 9

x = 9/4.
