4squared 3, 3/4 is what I got
Answer: 4 gallons will be needed.
Step-by-step explanation:
The bottom of the pool is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = Length × width
Olympic-sized swimming pool of uniform depth measures 50 meters by 21 meters. The area of the bottom would be
Area = 50 × 21 = 1050 m²
The bottom of the pool is to be treated with a sealer, and one gallon of the sealer covers 300 square feet of surface. This means that the number of gallons of sealer required for the job would be
1050/300 = 3.5gallons Approximately 4 gallons to the nearest gallon
Hey!
Into an equation:
9 - 4x = 2x
adding 4x on both sides
9 = 6x
dividing by 6 on both sides
9 / 6 = x
3 / 2 = x
x = 1.5
Hope helps!
