Answer:

10units^2

Explanation:

Unshaded Right Triangle

$A=(ab)/(2) \\=(4*2)/(2) \\=4units^2$

Whole Triangle

$A=(ab)/(2) \\=(4*7)/(2)\\ =14units^2$

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

$A=(h_(b)b)/(2) \\=(4*5)/(2)\\ =10units^2$
