Question 30128: THE COST FOR PAINT TO COVER BOTH SIDES OF A LARGE ROAD-SIDE SIGN (FRONT SIDE AND BACK SIDE) WAS $150. A 5-GALLON CAN OF PAINT COSTS $25 AND WILL COVER 250 SQUARE FEET.

ASSUMING IT REQUIRES ALL THE PAINT TO PAINT BOTH SIDES THEN ONE SIDE HAS 750 SQUARE FEET BECAUSE 150/25=6 GALLONS TIMES 250 SQUARE FEET = 1500 SQUARE FEET.
THE AREA OF ONE SIDE IS (35+40)/2 OR 37.5 FEET 37.5H=750 OR H=750/37.5 OR
H-20.
