Area of Rectangles and Triangles

The area of a rectangle is calculated using the formula: $$A = l \times w$$ , where A is the area, l is the length, and w is the width.

The area of a triangle is calculated using the formula: $$A = \frac{1}{2}bh$$ , where A is the area, b is the base, and h is the height.

The area is calculated as follows: $$A = l \times w = 8 \times 4 = 32 \text{ in}^2$$ .

The area is calculated as follows: $$A = l \times w = 15 \times 20 = 300 \text{ in}^2$$ .

The area is calculated as follows: $$A = l \times w = 9 \times 8 = 72 \text{ in}^2$$ .

The area is calculated as follows: $$A = \frac{1}{2}bh = \frac{1}{2} \times 10 \times 6 = 30 \text{ in}^2$$ .

The area is calculated as follows: $$A = l \times w = 12 \times 5 = 60 \text{ in}^2$$ .

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

The unit of measurement for area is typically square units, such as square inches (in²), square feet (ft²), or square meters (m²).

To convert square inches to square feet, divide the number of square inches by 144, since there are 144 square inches in a square foot.
