Question

6. The length of a rectangle is twice the
breadth. If its perimeter is 60 metres, then
find its length​

Answer 1

Step-by-step explanation:

let breadth be x m.

then,length=2xm.

perimeter =60 m.

=>2(3x)=60

x=10 m.

breadth of the rectangle =10 m.

length of the rectangle=20 m.

Answer 2

Answer:

= (2L+2b) =60m (l=2b(given))

2(2b)+2b=60

6b=60

b=60/6

b=10 therefor l=2*10=20 Ans
