Front

What is the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of all three sides.

Front

How do you find the perimeter of a triangle with sides of lengths 7 cm, 8 cm, and 10 cm?

Back

Perimeter = 7 cm + 8 cm + 10 cm = 25 cm.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

If the length of a rectangle is 16 cm and the width is 8 cm, what is the area?

Back

Area = 16 cm × 8 cm = 128 square centimeters.

A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number).

Front

How do you multiply fractions?

Front

What is the definition of perimeter?

Back

Perimeter is the total distance around a two-dimensional shape.
