Question

Pedro is building a playground in the shape of right triangle. He wants to know the area of the playground to help him decide how much sand to buy. Find the area of the playground. 4 1/3yd is the height and 18yd is the base.

Answer 1

Solution:

The shape of the playground is a triangle.

$\text{ Area of a trinage= }\frac{1}{2}\text{ x base x height }$

For this question, base = 18yd

Height = 4 1/3 yd

It's area therefore is

$\begin{gathered} A\text{ = }\frac{1}{2}\text{ x 18 x 4}\frac{1}{3} \\ A=\frac{1}{2}\text{ x 18 x }\frac{\text{13}}{3} \\ A\text{ = }\frac{234}{6} \\ A=39yd^2 \end{gathered}$

The area of th playground is 39 square yards
