Question 13 (2 points) find the area of the composite figure. plz

Step-by-step explanation:

The Pick's theorem

Let P be a polygon in the plane whose vertices have integer coordinates. Then the area of P can be determined just by counting the lattice points on the interior and boundary of the polygon!

In fact, the area is given by

where i is the number interior lattice points, and b is the number of boundary lattice points.

Look at the picture.

i = 38

b = 14

Substitute:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
