Answer:
The length of the base is 340 ft and the width of the base is 135 ft
Step-by-step explanation:
Let
x -----> the length of the base
y ----> the width of the base
we know that
The perimeter of the rectangular base is
so
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
Concave
I hope this helps!
if the length is 8ft and the width is (7+x) then the area would be 56+8x, if x is unknown.
