Answer 1

Answer:

split it into two shapes

Step-by-step explanation:

you will get a rectangle and triangle, evaluate areas.

Answer 2

Answer:

84m

Step-by-step explanation:

First split the shape up. There can be rectangle and then a triangle at the top.

Find the area of the rectangle first:

12 * 4 = 48.

Rectangle area 48m

Now find the area of the triangle at the top:

The base of the triangle is 12. The height would be 10-4 which gives you the height of 6.  So, 12 * 6 divided by 2 would give you the area of the triangle.

12 * 6 = 72, 72/2 = 36

Triangle Area 36m

Now add the two areas up: 48 + 36 = 84

So the area of the polygon is 84m
