the perimeter of a rectangle
is 76ft. the length of the rectangle is 2ft more than 5times the width.
what are the dimensions of the rectangle?

Sagot :

Lance1viz
x=width
2ft+5x=length
76ft=perimeter
p=2(l+w)
76ft=2(2ft+5x+x)
76ft=2(2ft+6x)
76ft=4ft+12x
76-4ft=12x
72ft=12x
72/12=12x/12
6=x
the width is 6 while the length is 32..check: P=2(l+w)
                                                                P=2(6+32)
                                                                P=2(38)
                                                                P=76 :D

perimeter=76ft.
length=5x+2
width=x

76=2(5x+2+x)
76=2(6x+2)
76=12x+4
12x=76-4
12x=72
x=6
width is 6
5x+2=5(6)+2
       =30+2
       =32
length is 32
76=2(36+6)
76=2(38)
76=76 correct
