Question

A square piece of plastic has sides that are 18 centimetres long. What is the piece of plastic's area?

Answer 1

To calculate the area of a square, you need to multiply the length of one side by itself. In this case, the side length of the square piece of plastic is 18 centimeters.

Area = side length * side length
Area = 18 cm * 18 cm
Area = 324 square cm

Therefore, the area of the square piece of plastic is 324 square centimeters.

Answer 2

324
`cm^(2)`

Explanation:

Area is the length multiplied by width. In the case of a square, both sides are the same so it would simply be 18 x 18 or
`18^(2)` which equals 324, but make sure to adds units,
`cm^(2)`. Hope this helps
