Answer:
add up all the sides!!
6+3+3+3+5+12+4+6=38
so the perimeter is 38 ft
Answer & Explanation:
For this question, you need to figure out the length and the width because the area is directly related to them (A = l*w).
What we do know is that the perimeter is 36 inches. Since the perimeter is equal to P = 2l + 2w, we can say:
P = 36 = 2(3 + 2w) + 2(w), where the length l is 3 + 2w
Solve for w first, then solve for l. Use these values to find the area.

Surface area is the area of all the surfaces we can touch
2a)
1/2*5*3+1/2*4*3+6*4+6*5 which is
67.5
b) 2*(1/2*10*6)+12*6+12*10 which is
252
it equals -1
you can think of it as 7-6=1 and at the end you can just add the negative sign
Hope it helps :))
