SURFACE Area = 2B (base) + P (perimeter of base)* h (height)
LATERAL Area = p*h
1. LA = 3(10*14)
3 faces of triangle
LA = 420 sq in
B = 1/2 8*12
B = 48 sq in
SA = 420 + 2(48)
SA = 516
Answer 516 sq in
2. LA = 5*14*3
LA = 210 sq ft
B = 1/2 8*3
B = 12 sq ft
SA = 210 + 2(12)
SA = 234
Answer 234 sq ft
3. LA = 20*17*3
LA = 1020 sq yd
B = 1/2 15*16
B = 120 sq yd
SA = 1020 + 2(120)
SA = 1260
Answer 1260 sq yd
Answer
28,800$
Step-by-step explanation:
480 x 4 = 1920 x 3 = 5760 x 5 = 28800
M= y2-y1/x2-x1
Line 1: 3-(-5) / 0-4 = -2
Line 2: 5-11 / (-1)-(-4) = -2
Since the slopes are the same they are parallel
