1. what is the area of this polygon?

2. what is the area of this polygon?

43.5 units²

45.5 units²

46.5 units²

49.5 units²

Part 1) The area of the polygon is

Part 2) The area of the polygon is

Step-by-step explanation:

Part 1) we know that

The area of the figure is equal to the area of rectangle GPST plus the area of triangle PES

Observing the graph

Find the area of rectangle

Find the area of triangle

The area of the figure is equal to

see the attached figure N 1 to better understand the problem

Part 2) we know that

The area of the figure is equal to the area of two triangles  plus the area of a trapezoid

Observing the graph

Find the area of triangle 1

Find the area of triangle 2

Find the area of trapezoid

The area of the figure is equal to

see the attached figure N 2 to better understand the problem

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
