Answer:
SA = 105 in^2
Step-by-step explanation:
To find surface area, find the area of all the shapes and add it all together. This shape has 4 triangle faces. They are all the same. So we can find one of them and times by 4.
Area of a triangle:
A = 1/2b•h
= 1/2• 5 • 8
= 1/2 • 40
= 20
One triangle has area 20, so times by 4 (bc four triangles)
4•20
= 80
Area of square 5•5
= 25
Add the areas:
80 + 25
= 105 sq in

Step-by-step explanation:
Step-by-step explanation:
a) D=(-1,5) E=(-3,1)
b) you do it by adding B coordinates with each other and C coordinates with each other then comparing how its related to D coordinates and E coordinates. B=2+6=8
C= -2-2= -4 D= -1+5= -4 E=-3+1= -2.
or tou can try another method which is knowing the length of each line.
