Area of a Triangle

The formula for the area of a triangle is $$A = \frac{b \times h}{2}$$ , where 'b' is the base and 'h' is the height.

We use squared units to show area, such as mm², ft², or in².

The area is calculated as follows: $$A = \frac{10 \times 5}{2} = 25 cm²$$ .

Using the formula $$A = \frac{b \times h}{2}$$ , we can rearrange it to find height: $$h = \frac{2A}{b} = \frac{2 \times 30}{10} = 6 in$$ .

The area is $$A = \frac{8 \times 4}{2} = 16 m²$$ .

The area is $$A = \frac{12 \times 10}{2} = 60 ft²$$ .

The area is $$A = \frac{6 \times 9}{2} = 27 cm²$$ .

Using the formula $$A = \frac{b \times h}{2}$$ , we find base: $$b = \frac{2A}{h} = \frac{2 \times 50}{5} = 20 m$$ .

The area is $$A = \frac{15 \times 8}{2} = 60 in²$$ .

The area is $$A = \frac{20 \times 10}{2} = 100 cm²$$ .
