keep the sign under 20 square feet to adhere to zoning laws.
If the base of the sign is 20 feet, what is the maximum height of the triangular sign?
:
.5*b*h = A
:
.5*20*h < 20
:
10h < 20
h < 20%2F10
h < 2 ft, height of the sign

area=1/2bh
20=1/2*20*h
1=1/2h
2=h
Are you sure you have the right numbers?
20 foot base and a 2 foot height seems rather odd for a triangular sign
