Question

Find the area of the triangle.

Answer 1

Answer:

$10units^2$

Step-by-step explanation:

Unshaded Right Triangle

$A=\frac{ab}{2} \\=\frac{4*2}{2} \\=4units^2$

Whole Triangle

$A=\frac{ab}{2} \\=\frac{4*7}{2}\\ =14units^2$

Shaded triangle

$14-4=10units^2$

If you dont want as many steps, just calculate the triangle and dont worry about the right triangle the formula is

$A=\frac{h_{b}b}{2} \\=\frac{4*5}{2}\\ =10units^2$
