(30 points need done asap! ) use the irregular polygon below. show all work. a. find the perimeter b. find the area show you work you so much! and need correct answer

see explanation

Step-by-step explanation:

The perimeter is the length of all 6 sides of the polygon.

Note that the 2 unknown sides are

8 - 4 = 4 mm and 8 - 2 = 6 mm

Starting with the left side

Perimeter = 8 + 2 + 4 + 6 + 4 + 8 = 32 mm

The polygon can be split into 2 rectangles.

The lower rectangle with sides of 8 and 4

and the upper rectangle with sides 2 and 4

Area = (8 × 4) + (2 × 4) = 32 + 8 = 40 mm²
