The length of a rectangle is three times its width. if the perimeter of the rectangle is 64 cm, what is the area?

before area, we need to calculate length & width

let, width = x

length = 3x

so, 64 = 2(3x+x)

8x = 64

x = 8 (width)

3x = 24 (length)

So, area would be: 24 * 8 = 192 cm²

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
