Question

Exercise 9.1 solve the following
The length of a rectangle is 2 m and its breadth is 1 m. Find its
perimeter​

Answer 1

Answer:

Breadth =x

Length =2x

Perimeter =72m

Perimeter =2(l+b)

⇒72=2(2x+x)

⇒72=6x

x=12

∴breadth=12m

length=24m

Answer 2

Answer:

6m

Step-by-step explanation:

length= 2m

breadth =1m

perimeter of rectangle= 2(l+b)

2(2+1)= 2×3= 6metre
