Step-by-step explanation:
To find the area of the shade region, considering the diagram, the diagonal of the rectangle has divided the figure into two equal half. So, one is shaded and the other not shaded. So the shaded region is a right angled triangle,. So the formula for finding the area of a triangle need to be applied.
Area. = 1/2 × b × h
= 1/2 × 10 × 8
= 40in²
