1. In the figure given, calculate the area that is shaded.

8.71

Step-by-step explanation:

the area that is shaded is a big shape then two smaller shapes taken out of it

that means you can find the area of the big shape ignoring that there are holes then subtract the area of the holes

big shape side length is 5*2

=10

small shape 1:

0.3*0.3

=0.09

small shape 2:

0.6*2

=1.2

10-(0.09+ 1.2)

10-(1.29)

=8.71

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
