Three strips of 2-yard wide outdoor carpet are used to cover a sidewalk one is 3.5 yards long ii is 45% longer than the first and the third is 6 1/4 yards long how long are the three carpets placed end-to-end

The answer for this problem is 14.825

Step-by-step explanation:

There are about three steps for this problem

The first is finding out what is 45% of 3.5 yds. You do this by multiplying 3.5 and .45 and you get 1.575

The second step is finding the second carpets length. All you have to do is add the number we got from multiplication which is 1.575 to 3.5 and you get 5.075. The reason we added those numbers is because the problem says the second carpet is 45% "longer" than the first carpet.

The third and final step is to add up all three values and you get 14.825!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
