Question

write an equation for the area, a, of the triangle shown.
a = \frac{1}{2}\cdot12\cdot20
now find the area of the triangle.
a = \square ft^{2}

Explanation:

Step1: Calculate the product of 12 and 20

$$12\times20 = 240$$

Step2: Multiply the result by \(\frac{1}{2}\)

$$\frac{1}{2}\times240=120$$

Answer:

\(120\)
