Answer:
B
Step-by-step explanation:
1/4.6+1/2=1/3.6
6/4+1/2=2
8/4=2
So B
5/9, 5 ÷ 9
h/16, h ÷ 16
w + 8 ÷ 3,
x - 2 ÷ y,
300ft^2
Total surface area = Area of base + (1/2) x perimeter of base x slant height
Area of base = length² = 10 x 10 = 100
Perimeter of base = 2 ( length + breadth)
2 x 20 = 40
slant height = 10
100 + (1/2) x 40 x 10 = 300 ft^2
