Area (Missing Side)

Front

What is Area?

Back

Area is the amount of space inside a shape, measured in square units.

Front

How do you find the area of a rectangle?

Back

Multiply the length by the width (Area = Length x Width).

Front

What is a missing side in geometry?

Back

A missing side is a side length of a shape that needs to be calculated to find the area or perimeter.

Front

If a rectangle has a length of 6ft and an area of 18ft², what is the missing width?

Back

3ft (Area = Length x Width, so Width = Area / Length = 18ft² / 6ft).

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 x Base x Height.

Front

If a triangle has a base of 4ft and a height of 3ft, what is its area?

Back

6ft² (Area = 1/2 x 4ft x 3ft).

Front

What is the perimeter of a rectangle?

Back

The perimeter is the total distance around the rectangle, calculated as 2 x (Length + Width).

Front

If a rectangle has a length of 5ft and a width of 2ft, what is its perimeter?

Back

14ft (Perimeter = 2 x (5ft + 2ft)).

Front

What does 'square units' mean?

Back

Square units are the units used to measure area, such as square feet (ft²) or square meters (m²).

Front

How can you check if your area calculation is correct?

Back

You can compare it with the known dimensions or use a different method to calculate the area.
