Hi there!
The problem statement describes the dimensions. The base length is 15 ft; the height is 10 ft.
The area of a parallelogram is the product of base length and height, just as it is for a rectangle.
A = bh
A = (15 ft)(10 ft) = 150 ft²
Mr Morris should purchase 150 ft² of material.
_____
If you compare the area to a 15 ft by 10 ft rectangle, you see the "excess" triangle at the left end just matches the "missing" triangle at the right end. The A=bh formula still works even if the top and base are offset by more than the width of the base.

1-(5 times ?)+(24-?) I don't know
2√4a³b³c³
Basically, find the square root of everything inside.
Let's do this in small chunks.
√4 = 2
So, take out the square, and multiply it by 2, because 2 if on the OUTSIDE of the whole radical.
So, now we have :
4√a³b³c³
Take out the square of a³, b³, and c³
4abc√abc
~Hope I helped!~
Answer:
b = 4.6 ft
h = 2.3 ft
Step-by-step explanation:
The volume of the tank is given by:
Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.
The surface area can be written as:
The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:
The value of h is then:
Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.
