What is the definition of perimeter?

Back

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

Front

How do you calculate the area of a square?

Back

Area = side × side (A = s²). For example, if each side is 6 cm, the area is 6 cm × 6 cm = 36 cm².

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width). For example, for a rectangle 15 feet long and 21 feet wide, P = 2 × (15 + 21) = 72 feet.

Front

What is the area of a rectangle with a width of 4 feet and a height of 4 feet?

Back

Area = width × height = 4 ft × 4 ft = 16 ft².

If a sandbox has an area of 60 square meters and a width of 10 meters, how do you find the length?

Back

Length = Area ÷ Width. So, Length = 60 m² ÷ 10 m = 6 m.

Front

What units are used to measure area?

Back

Area is measured in square units, such as square meters (m²), square centimeters (cm²), or square feet (ft²).

Front

What is the formula for the area of a triangle?
