Area and Perimeter ACT Questions

Front

What is the formula for the surface area of a cube?

Back

The surface area (SA) of a cube is given by the formula: SA = 6a^2, where 'a' is the length of an edge.

Front

If the edge length of a cube is tripled, how does the surface area change?

Back

If the edge length is tripled, the new surface area is 9 times larger than the original surface area.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is given by the formula: P = 2(length + width).

Front

How do you calculate the perimeter of a polygon?

Back

To calculate the perimeter of a polygon, sum the lengths of all its sides.

Front

What is the relationship between the area and perimeter of a rectangle?

Back

The area is the space inside the rectangle (A = length × width), while the perimeter is the total distance around it.

Front

What is the formula for the area of a rectangle?

Back

The area (A) of a rectangle is given by the formula: A = length × width.

Front

How do you find the width of a rectangle if the area and length are known?

Back

Use the formula: width = Area / length.

Front

What is the formula for the area of a parallelogram?

Back

The area (A) of a parallelogram is given by the formula: A = base × height.

Front

What is the perimeter of a square with a side length of 's'?

Back

The perimeter (P) of a square is given by the formula: P = 4s.

Front

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

Back

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