Perimeter of rectangle is 2(l+b)

=2(3b + b) = 96

=8b = 96

= b=96/8 = 12m

Hope it helps

Answer 2

Answer:

length=36 m

width=12m

Step-by-step explanation:

length is three times the width=3x

width=x

perimeter of rectangle=2(l+b)

96m=2(3x+x)

(3x+x)=96/2

(3x+x)=48

4x=48

x=48/4

x=12

length=3x=12*3

=36m

width=x=12m
