How do you find the area of a composite figure?

Back

To find the area of a composite figure, divide it into simpler shapes, calculate the area of each shape, and then sum those areas.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What is the formula for the area of a circle?

Back

Area = π × radius².

Front

How do you calculate the perimeter of a composite figure?

Back

To calculate the perimeter, add the lengths of all the outer sides of the figure.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.

Front

If a rectangle has a length of 10 m and a width of 5 m, what is its area?

Back

Area = 10 m × 5 m = 50 m².

Front

If a triangle has a base of 8 m and a height of 5 m, what is its area?

Back

Area = 1/2 × 8 m × 5 m = 20 m².

Front

What is the perimeter of a rectangle with lengths of 4 m and 6 m?

Back

Perimeter = 2 × (length + width) = 2 × (4 m + 6 m) = 20 m.
