Question

Use π = 3.14. Determine the area and perimeter of the figures below. (Use π = 3.14. Round your answers to two decimal places.)Assume that
a = 12 m, b = 10 m, c = 16 m, and d = 20 m.

Answer 1

Answer 2

Okay this one should be fine to solve as well.
So I hope that you've also notice that this shape is comprised of two smaller shapes, a rectangle and a right-angled Triangle

Answer 3

Like always, we'll solve area first!

Answer 4

So like previously, I'm going to split the diagram into two smaller areas; Area 1 and Area 2
We are going to solve for Area 1 first and that's the rectangle :)

Answer 5

The area of the rectangle is A = Length x Height

Answer 6

So A = 12 x 20
= 240 Units Squared

Answer 7

Area 2 will be that small right-angled Triangle

Answer 8

So it will be A = 1/2 x (4)(10)
= 20 Units Squared

Answer 9

so 260= area

Answer 10

Thus we can add the two areas together now, like so:
A = Area 1 + Area 2
= 20 + 240
= 260 units squared

Answer 11

now perimeter

Answer 12

Okay the perimeter

Answer 13

The perimeter is almost solve, although he have to find this really small side first using Pythagoras formula first

Answer 14

x^2 = 10^2 + 4^2
= 100 + 16
x = Sqrt[116]
= 10.77 Units

Answer 15

So now since we have solved this smaller side, we can now add all the other sides together now!

P = 12 + 20 + 16 + 10.77 + 10
= 68.77 Units

Answer 16

that is correct. thank you

Answer 17

Cool :)
