Lesson 6: Area and Perimeter

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its three sides: P = a + b + c.

Front

How do you calculate the perimeter of a rectangle?

Back

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

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 * base * height.

Front

What is the definition of a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

How do you find the perimeter of a quadrilateral?

Back

The perimeter of a quadrilateral is the sum of the lengths of all four sides: P = a + b + c + d.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length * width.

Front

What is the difference between perimeter and area?

Back

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

Front

How do you calculate the perimeter of a right triangle?

Back

The perimeter of a right triangle is calculated by adding the lengths of all three sides: P = a + b + c.

Front

What is the formula for the area of a trapezoid?

Back

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