Step-by-step explanation:
area of a trapezoid = (a+b)* h/2
since the distance between two parallel sides is 15, that would be your height
plug everything in and you get:
480 = (20 + b) *15/2
b = 44
Answer:
b
Step-by-step explanation:
Surface of the earth =3959×3.14
=12,437.565
if 20%is suitable so we multiply it by the surface
12,437.565×0.2=2,487.513 per people
2,487.513/7,700,00,00
So I think it will be the closest to b
