Area and Perimeter

Front

What is the perimeter of a rectangle?

Back

The perimeter is the total distance around the rectangle, calculated as P = l + l + w + w, where l is the length and w is the width.

Front

What is the area of a rectangle?

Back

The area is the amount of space inside the rectangle, calculated as A = l x w, where l is the length and w is the width.

Front

What is the formula for calculating the perimeter of a rectangle?

Back

P = l + l + w + w or P = 2l + 2w.

Front

What units are used to measure area?

Back

Area is measured in square units, such as square feet (sq ft) or square meters (sq m).

Front

What units are used to measure perimeter?

Back

Perimeter is measured in linear units, such as feet (ft), inches (in), or meters (m).

Front

If a rectangle has a length of 5 ft and a width of 3 ft, what is its perimeter?

Back

P = 5 + 5 + 3 + 3 = 16 ft.

Front

If a rectangle has a length of 4 ft and a width of 2 ft, what is its area?

Back

A = 4 x 2 = 8 sq ft.

Front

What could be the dimensions of a rectangle with an area of 20 sq ft?

Back

Possible dimensions include 5 ft x 4 ft or 10 ft x 2 ft.

Front

How do you find the perimeter of a square?

Back

For a square, the perimeter is P = 4s, where s is the length of one side.

Front

What is the relationship between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around it.
