Perimeter and Area (Released STAAR) 4th

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around the rectangle, calculated by adding the lengths of all four sides. Formula: P = 2(length + width).

Front

What is the area of a rectangle?

Back

The area of a rectangle is the amount of space inside it, calculated by multiplying the length by the width. Formula: A = length × width.

Front

What is the formula for the area of a square?

Back

The area of a square is calculated by squaring the length of one of its sides. Formula: A = side × side.

Front

How do you find the perimeter of a square?

Back

The perimeter of a square is found by adding the lengths of all four sides or by multiplying one side by 4. Formula: P = 4 × side.

Front

If a rectangle has a length of 5 units and a width of 3 units, what is its area?

Back

Area = length × width = 5 × 3 = 15 square units.

Front

If a square has a side length of 4 units, what is its perimeter?

Back

Perimeter = 4 × side = 4 × 4 = 16 units.

Front

What is the difference between perimeter and area?

Back

Perimeter measures the distance around a shape, while area measures the space inside a shape.

Front

If a rectangle has a perimeter of 20 units and a length of 6 units, what is its width?

Back

Perimeter = 2(length + width) => 20 = 2(6 + width) => width = 4 units.

Front

What is the area of a rectangle with a length of 10 units and a width of 2 units?

Back

Area = length × width = 10 × 2 = 20 square units.

Front

How do you calculate the perimeter of a triangle?

Back

The perimeter of a triangle is calculated by adding the lengths of all three sides. Formula: P = side1 + side2 + side3.
