Answer 2

Answer:

Let the height be x feet and the base be y feet

1st equation:

2(x+y)=80

x+y=40

2nd equation:

x=4y-5

x-4y=-5

Solution of the 1st and the 2nd equation:

x+y=40.1

x-4y=-5.-1

_________

x+y=40

-x+4y=5

_________

5y=45

y=9

x+y=40

x+9=40

x=40-9

x=31

.

. . The height is 31 feet and the base is 9 feet
