Question

5. If the length of a rectangle is twice its breadth and its perimeter is
120m,thenfind its dimensions ???​

Answer 1

Step-by-step explanation:

let the breadth of rectangle be x

therefore length=2(x)=2x

perimeter=2(l+b)

P=2(2x+x)

120=2(3x)

120=6x

x=120/6

x=20m

breadth=x

breadth=20m

length=2x

length=2(20)

Length=40m

Answer 2

Answer:

l=40m

b=20

Step-by-step explanation:

let the breadth be x

l=2x

perimeter=120

perimeter of rectangle=2(l+b)

=2(2x+x)

=2*3x

120=6x

120/6=x

x=20

b=x

b=20m

l= 2b

= 2×20

40m
