Question

Identify the polynomial that represents the shaded area of the figure.

Answer 1

10a- 41

Explanation:

shaded area of the figure

=(a+4) (a-4) - (a-5)2

=a2 -16 - (a2-10a+25)

=a2 - 16 - a2 +10A-25

=10a- 41

Answer 2

Area of shaded region2
= (a+4) (a-4) - (a-5)2
= a2 - 16- (a2-10a+25)
= a2 -16-a2+10a-25
=10a-41

Answer : 10a-41
