Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. clear check how many pounds of gravel does it take to cover one sq
timama [110]

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

From given question,

252 lb = 36 ft²             ..........(1)

The number of pound for an area of 1 square foot is calculated as follows:

x = 1 ft²                       .......(2)

The area and the amount of gravel are illustrations of proportions.

From (1) and (2) we get an equation,

⇒ x × 36 = 252 × 1

⇒ x = 252/36

⇒ x = 7 lb

We need to find the area that could be covered with 315 lb of gravel

The area to be covered with 315 lb gravel is calculated as follows:

315 lb = y               ............(3)

From (1) and (3) we get an equation,

⇒ y × 252 = 36 × 315

⇒ y = 45 ft²

Therefore, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
