Question

The length and breath of a rectangle are in the ratio of 2:1 find its area if its perimeter is 60 m

Answer 1

Answer:

Let the ratio be x.

So the length and breadth are 2x and x.

Perimeter of rectangle = 2 (l+b)

= 2 (2x+x)= 60 cm

2*3x= 60

6x = 60

x= 10

So.the sides are 2x= 2x 10 = 20 cm

and x= 10cm

So, area of rectangle = lxb

20x 10 = 200cm square........

Answer 2

Answer:

200m²

Step-by-step explanation:

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 perimeter 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
