Mr. West is painting his front sidewalk to make it colorful. The total area is 24 square feet. What are the possible dimensions

ryzh [129]

Answer:

All possible dimensions are: 1ft × 24ft = 24 $ft^{2}$ , 2ft × 12ft = 24 $ft^{2}$ , 3ft × 8ft = 24 $ft^{2}$ , 4ft × 6ft = 24 $ft^{2}$ , 6ft × 4ft = 24 $ft^{2}$ , 8ft × 3ft = 24 $ft^{2}$ , 12ft × 2ft = 24 $ft^{2}$ , or 24ft × 1ft = 24 $ft^{2}$ .

Step-by-step explanation:

With the assumption that the sidewalk has a rectangular shape:

Area of a rectangle = length × width

From the question, the total area = 24 $ft^{2}$ .

⇒ length × width = 24 $ft^{2}$

So, all possible combinations are:

i. 1 ft × 24 ft = 24 $ft^{2}$

ii. 2 ft × 12 ft = 24 $ft^{2}$

iii. 3 ft × 8 ft = 24 $ft^{2}$

iv. 4ft × 6 ft = 24 $ft^{2}$

v. 6ft × 4ft = 24 $ft^{2}$

vi. 8ft × 3ft = 24 $ft^{2}$

vii. 12ft × 2ft = 24 $ft^{2}$

viii. 24ft × 1ft = 24 $ft^{2}$
