Area/Perimeter Review

Front

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

Back

Area = length x width

Front

What is the perimeter of a shape?

Back

The total distance around the shape.

Front

If a rectangle has a length of 5 cm and a width of 4 cm, what is its area?

Back

Area = 5 x 4 = 20 cm²

Front

What is the perimeter of a rectangle with a length of 6 cm and a width of 3 cm?

Back

Perimeter = 2(length + width) = 2(6 + 3) = 18 cm

Front

If a square has a side length of 4 cm, what is its area?

Back

Area = side x side = 4 x 4 = 16 cm²

Front

What is the area of a triangle with a base of 6 cm and a height of 4 cm?

Back

Area = 1/2 x base x height = 1/2 x 6 x 4 = 12 cm²

Front

If the perimeter of a rectangle is 24 cm and the length is 10 cm, what is the width?

Back

Perimeter = 2(length + width) => 24 = 2(10 + width) => width = 2 cm

Front

What is the area of a shape measured in square units?

Back

Area is measured in square units, like cm² or m².

Front

If a pentagon has sides measuring 5 cm, 7 cm, 8 cm, 6 cm, and x cm, and the perimeter is 35 cm, what is x?

Back

x = 35 - (5 + 7 + 8 + 6) = 9 cm

Front

What is the difference between area and perimeter?

Back

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