Question

b. The breadth of rect
angle is 2cm. less then its length and it' perimeter is 24cm.
Find the length and breadth of rectangle.​

Answer 1

Answer:

let Length=l

therefore breadth=l-2

A/Q

P=24

2(l+b)=24

2(l+l-2)=24

2(2l-2)=24

4l-4=24

4l=28

l=28/4

=7

Therefore length =l=7cm

breadth=b=l-2=7-2=5cm

Answer 2

Answer,

length = 7

breadth = 5

Check

we know,

Perimeter =2(l+b)

therefore,

= 2(7+5)

= 2×12

= 24
