Question

Find the area of the triangle 8.2 yd 21 yd

Answer 1

The base of triangle is b = 21 yd.

The height of triangle is h = 8.2 yd.

The formula for the area of triangle is,

`A=(1)/(2)\cdot b\cdot h`

Substitute the given value in the formula to determine the area of triangle.

`\begin{gathered} A=(1)/(2)\cdot8.2\cdot21 \\ =4.1\cdot21 \\ =86.1 \end{gathered}`

Thus , area of trinagle is 86.1 yard square.
