Find the perimeter and area of the polygon shown below. the polygon is a trapezoid made up of a rectangle and a right triangle. the rectangle is 20 feet long and 15 feet wide. the right triangle joins the rectangle at a side that is 15 feet wide, and this is the height of the triangle. the base of the triangle is 8 feet and the hypotenuse is 17 feet.

Perimeter =110 feet

Area=360 feet^2

Step-by-step explanation:

Firstly, we can draw diagram

Perimeter:

we will find perimeter of rectangle and right angled triangle

and then we can add them to find perimeter

Perimeter of rectangle = 15+20+15+20

Perimeter of rectangle = 70

Perimeter of triangle = 17+8+15

Perimeter of triangle = 40

so,

total perimeter = (Perimeter of rectangle)+(Perimeter of triangle)

total perimeter =70+40

total perimeter =110 feet

Area:

We can find area of rectangle and area of right angled triangle

and then we can combine them

Area of rectangle is

Area of triangle is

now, we can combine

total area =300+60

total area =360 ft^2

answer: the answer is 23
