Question

FUL
11. Length of a rectangle is 16 cm less than twice its breadth. If the perimeter of
rectangle is 100 cm, find its length and breadth.​

Answer 1

Answer:

Let length of rectangle =L

Breadth =b

Perimeter =100 cm

Now L=2b-16

2(L+b)=100

2b-16+b=100%2

3b=50+16

b=22

L=2×22-16

=44-16

=28

Answer 2

Step-by-step explanation:

let b=x

l=2x-16

perimeter of rectangle=2(l+b)

100=2(2x-16+x)

50=3x-16

66=3x

x=22

b=22

l=2×22-16=44-16=28
