Question

Find the perimeter and area of the following composite figure. GEOMETRY!! HELPPP PLS

Answer 1

p=80 a=252

Explanation:

Add all side lengths to get the perimeter.

20+12+12+8+20+8=80

Perimeter is 80

Area of a trapezoid is average of parallel lines*height

((20+36)/2)*9=252

Area=252

Answer 2

perimeter=80 area=252

Explanation:

The perimeter is the total length of the boundary of the shape added together: 12+20+12+8+20+8=80

The area is the value of the space inside the shape: the rectangle would be 20*9=180 plus the two triangles: (8*9)/2 = 36 180+72=252
