Answer:
45 square units
Step-by-step explanation:
You can cut the yellow figure into a triangle (4 by 5) and a rectangle (7 by 5).
Using the formula [tex]\frac{1}{2} *b*h[/tex] and [tex]l*w[/tex] area formulas, we get:
[tex]\frac{1}{2} *4*5+7*5=\\2*5+7*5=\\10+35=\\45[/tex]
The area shaded in yellow is 45 square units
