Find the area of the shaded region

PIT_PIT [208]

Answer:

Area of the shaded region= $500inch^2$

Step-by-step explanation:

Area of the shaded region= Area of the triangle- Area of the rectangle

Dimensions of the triangle:

Base= 40 inch

Height= 40 inch

Area of a triangle= $\frac{1}{2}*Base*Height$

$=\frac{1}{2}*40*40\\\\ =\frac{1}{2} *1600\\\\=800 inch^2$

Area of the rectangle= Length*Width

Length=30 inch

Width=10 inch

Area:

$= 30*10\\\\=300 inch^2$

Area of the shaded region= $800-300= 500 inch^2$
