Question

The length and breadth of a rectangle are in the ratio 3:2. The perimeter of the rectangle is
10 cm, then its length is……………………. (in cm)
a) 2 cm
b) 3 cm
c) 5 cm
d) 4 cm

pls answer i will mark you brainliest

Answer 1

Answer:

let, the length=3x

the breadth = 2x

perimeter of rectangle = 2(l+b)

=2(3x+2x)

=6x+4x=10

=10x=10

= x= 10/10

= x=1

length= 3cm (b)

Answer 2

3cm

perimeter of rectangle=2(l+b)

perimeter of given rectangle=10cm

length =3x

breadth=2x

10cm=2(3x+2x)

10cm=2(5x)

10cm=10x

x=10/10

x=1

length=3x=3*1=3cm

breadth 2x=2*1=2cm.

I hope this helpful.
