Question

A triangular park has (5,4),(0,0) and(5,0) vertices, 1.Find the area of this park by plotting them on the graph 2.if....

Answer 1

Let's name respected vertices as A,B and C.
So, the distance between A and C is 4
And distance between B and C is 5

By using equation
$\frac{1}{2 } \times b \times h$
$\frac{1}{2} \times 5 \times 4$
$5 \times 2$
$10cm {}^{2}$
