Question

the perimeter of a rectangle is 48cm .the length is 3 more than twice the breath . find the length and the breath .

Answer 1

Answer:

let

Step-by-step explanation:

the breadth be x

then length be 2x +3

now,

perimeter of rec.=2(l+b)

48=2(2x+3+x)

2(3x+3)

Answer 2

Answer:

Length is 17 cm and breadth is 7 cm.

Step-by-step explanation:

L=2*b+3 [Given] [1]

Perimeter= 48cm

2(L+b)=48

2(2b+3+b)=48        [Dividing 2 by both sides]

3b =24 -3              [Subtracting 3 from both sides]

b=7 cm

from [1]

L= 2*7+3

L=17 cm
