Front

What is the formula to find the area of a rectangle?

Back

Area = length x width

Front

What is the formula to find the area of a square?

Back

Area = side x side or Area = side^2

Front

If a rectangle has a length of 8 m and a width of 3 m, what is its perimeter?

Back

Perimeter = 2(8 m + 3 m) = 22 m

Front

If a square has an area of 36 sq m, what is the length of one side?

Back

Length of one side = 6 m (since 6 m x 6 m = 36 sq m)

Front

What is the perimeter of a square with a side length of 5 m?

Back

Perimeter = 4 x 5 m = 20 m

Front

What is the difference between perimeter and area?

Back

Perimeter is the distance around a shape, while area is the space inside a shape.

Front

If the area of a rectangle is 20 sq m and the length is 5 m, what is the width?

Back

Width = Area / Length = 20 sq m / 5 m = 4 m

Front

What is the perimeter of a triangle with sides measuring 3 m, 4 m, and 5 m?

Back

Perimeter = 3 m + 4 m + 5 m = 12 m

Front

How do you find the area of a triangle?

Back

Area = (base x height) / 2
