Given a(-2,0); b(2,0); c(4,3); d(0,4); and e(-4,3) find the area and perimeter

If you graph the points and count the length you would get bases, 4 and 8 and the height 3

split it in two triangles like this http://prntscr.com/mtt4sq

then the triangle area formula base*height/2

8*3/2 = 12

4*3/2= 6

12+6=18

Now if we add the top triangle/s.

b*h/2

8*1/2=4

There are two triangles

The top half would equal 8.

18+8=26

The area would be 26

For perimeter:

We just need to find the hypotenuse since we know the height and the base of the triangle in the corner the base is 2.

Using a2+b2=c2

2^2+3^2=c^2

4+9=13^2

13^2=3.6

Now we know all 4 sides.

3.6+3.6+4=11.2

This is for the bottom half total.

For the top triangle hypotenuse:

a^2+b^2=c^2

4^2+1^2=c^2

16+1=c^2

17^2=4.1

11.2+8.2= 19.4

The perimeter is 19.4

Hope this helped. :)

u what ?

step-by-step explanation:

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
