The perimeter of a rectangle is 60 inches. If its length is three times its width find the dimesions

the Length is 22.5 inches, and width is 7.5 inches.

Step-by-step explanation:

Step 1

The perimeter of the rectangle is given as  

 P = 2L + 2W

 We were given tha length is 3 times the width,

so L = 3 W

 Replacing L by 3W in the equation of the perimeter becomes  

Step 2

 P = 2L + 2W  

2(3W) + 2W = 60

6W + 2W = 60

8W =60

 W = 60 /8

W = 7.5

Snce  L = 3W

L= 3 (7.5)

L = 22.5

Therefore the Length is 22.5 inches, and width is 7.5 inches.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

i believe a. 12x≥120 is the answer
