Answer:
A = 59 in²
Step-by-step explanation:
the area (A) of the shaded region is calculated as
A = area of outer triangle - area of inner triangle
= [tex]\frac{1}{2}[/tex] bh - [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
= [tex]\frac{1}{2}[/tex] × 13 × 14 - [tex]\frac{1}{2}[/tex] × 8 × 8
= 91 - 32
= 59 in²
