The other family is traveling at 900 miles per day while your family is traveling at 950 miles per day. So your family is traveling faster.
Recall that the volume of a regular prism is given by the area of the base times the height.
Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.
Recall that the are of a triangle is given by 1/2 base times height.
Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by
Multiply top equation by -2, then add equations so b drops out....solve for a...plug in a to get b
Answer:
Step-by-step explanation:
The height is connected to the base of 16cm
Area = b * h
b = 16
h = 5
Area = b * h
Area = 16 cm * 5 cm
Area = 80 cm^2
