Answer:
[tex]10units^2[/tex]
Step-by-step explanation:
Unshaded Right Triangle
[tex]A=\frac{ab}{2} \\=\frac{4*2}{2} \\=4units^2[/tex]
Whole Triangle
[tex]A=\frac{ab}{2} \\=\frac{4*7}{2}\\ =14units^2[/tex]
Shaded triangle
[tex]14-4=10units^2[/tex]
If you dont want as many steps, just calculate the triangle and dont worry about the right triangle the formula is
[tex]A=\frac{h_{b}b}{2} \\=\frac{4*5}{2}\\ =10units^2[/tex]
