4th Area & Perimeter

Front

What is the formula to calculate the perimeter of a rectangle?

Back

Perimeter = 2L + 2W (where L is length and W is width)

Front

If a square has a side length of 5 cm, what is its perimeter?

Back

Perimeter = 4S = 4 x 5 cm = 20 cm

Front

What is the area of a rectangle with a length of 10 cm and a width of 4 cm?

Back

Area = L x W = 10 cm x 4 cm = 40 cm²

Front

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

Back

Area = S x S (where S is the length of a side)

Front

If a rectangle has a perimeter of 30 cm and a length of 10 cm, what is its width?

Back

Perimeter = 2L + 2W; 30 = 2(10) + 2W; 30 = 20 + 2W; 2W = 10; W = 5 cm

Front

What is the perimeter of a polygon with sides measuring 3 cm, 4 cm, 5 cm, and 6 cm?

Back

Perimeter = 3 + 4 + 5 + 6 = 18 cm

Front

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

Back

Area = (Base x Height) / 2 = (6 cm x 4 cm) / 2 = 12 cm²

Front

What is the perimeter of a square with a side length of 8 cm?

Back

Perimeter = 4S = 4 x 8 cm = 32 cm

Front

If a rectangle has a length of 12 cm and a width of 3 cm, what is its area?

Back

Area = L x W = 12 cm x 3 cm = 36 cm²

Front

What is the perimeter of a rectangle that is 15 feet long and 10 feet wide?

Back

Perimeter = 2L + 2W = 2(15) + 2(10) = 30 + 20 = 50 feet
