Step-by-step explanation:
Given:
An aquarium,which is a right rectangular prism.
Length of the aquarium,

1.) Twenty five minus six
50=10+.2x so if you solve for x you get x=200. Hope this helps:)
Trapezoid, height 7, bases 5 and 6, so
area = (1/2) (6 + 5)(7) = 77/2 = 38.5
Answer: 38.5
As a check it's a 7×5 rectangle plus a 7×1 right triangle, so
A = 7×5 + 7×1/2 = 35 + 3.5 = 38.5, good
