Question

Find the area of this triangle. 30ft and 8ft.

Answer 1

Answer: 120 square feet

Explanation:

Area formula of triangle:

(height of triangle x length) divided by 2

`(30*8)/(2) =(240)/(2) =120`

Answer 2

120 ft²

Explanation:

`\boxed{\begin{minipage}{4 cm}\underline{Area of a triangle}\\\\$A=(1)/(2)bh$\\\\where:\\ \phantom{ww}$\bullet$ $b$ is the base. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}`

From inspection of the given triangle:

• b = 30 ft
• h = 8 ft

Substitute the given base and height into the formula to find the area of the triangle:

`\implies A=(1)/(2) \cdot 30 \cdot 8`

`\implies A=15 \cdot 8`

`\implies A=120\; \sf ft^2`

Therefore, the area of the given triangle is 120 ft².
