Question

Will give brainliest!! Using the measurements of the shapes.. determine the area and perimeter of the irregular polygon.

Answer 1

6+6+3+4.2+3+3+3 =ans

Answer 2

Answer:

3 + 3 + 4.2 = 10.2 perimeter

3 x 3 = 9, 9 divided by 2 = 4.5 is area

3 + 3 + 3 + 3 = 12 is perimeter (all sides are the same length since its a square)

3 x 3 = 9 is area

3 + 3 + 4.2 + 4.2 = 14.4 is your perimeter

3 x 2.9 = 8.7 is your area

6 + 6 + 8.5 = 20.5 is your perimeter

We need to find the height using the hypotenuse formula:

Half of 8.5 = 4.25

4.25^2 + 6^2 = 54.0625

Square root of 54.0625 is around 7.35

Now let's find the area:

8.5 x 7.35 x 1/2(basically just dividing by 2) = 31.2375 rounded = 31.24 is your area
