Area and Perimeter

Front

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

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

If a rectangle has a length of 10 feet and a width of 5 feet, what is its perimeter?

Back

The perimeter is 30 feet, calculated as P = 2(10 + 5) = 30.

Front

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

Back

The area (A) of a rectangle is calculated using the formula A = length × width.

Front

If a rectangle has a length of 8 feet and a width of 4 feet, what is its area?

Back

The area is 32 square feet, calculated as A = 8 × 4 = 32.

Front

What is the formula for calculating the area of a triangle?

Back

The area (A) of a triangle is calculated using the formula A = 1/2(base × height).

Front

If a triangle has a base of 6 feet and a height of 5 feet, what is its area?

Back

The area is 15 square feet, calculated as A = 1/2(6 × 5) = 15.

Front

What is the formula for calculating the area of a trapezoid?

Back

The area (A) of a trapezoid is calculated using the formula A = 1/2(base1 + base2) × height.

Front

If a trapezoid has bases of 10 feet and 6 feet, and a height of 4 feet, what is its area?

Back
