Question

the length and breadth of a rectangle is 3:2. if perimeter of rectangle is 100m. find area of rectangle ​

Answer 1

Answer: we have to find the length and breadth of the rectangle

100m=3x:2x

100m=5x

x=20m

Length=3*20 = 60

Breadth=20*2=40

Area =l*b=60*40

=2400m sq.

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

The length And breadth of a rectangle is 3:2

Let their common multiple be x

Therefore, length=3x and breadth =2x

As given,

2(l+b)= perimeter of rectangle

2(3x+2x)= perimeter of rectangle

2(5x)=100

5x=100/2

5x=50

x=50/5

x =10

Length=3x=3× 10cm=30

Therefore breadth= 2x= 2×10=20

Area of rectangle = length × breadth

Area of rectangle = 30× 20

Area of rectangle = 600sq.cm.
