Question

find the perimeter and the area of the following rectangles
lenght =240m
breath=120​

Answer 1

Answer:

Correct option is A)

Ratio of length and breadth is 2:1

Let x be the common factor

So the length is 2x

Breadth is x

The perimetr is given as 2(l+b)=60

x+2x=30

3x=30

x=10

Area is given as lb=x(2x)=2x

2

=2(100)=200

Answer 2

Answer:

720

Step-by-step explanation:

perimeter= 2*240+120

= 2*360

= 720 m
