Question

length of rectangular handset mobile is 3cm more than it's breadth if its perimeter is 34cm find the length and breadth​

Answer 1

Answer:

y:4+x

x+y:34

substitute y value in equation

x+4+x:34

2x+4 :34

2x: 34-4

2x : 30

x: 30/2

x: 15

Answer 2

Let the breadth be x
The length be x+3
Perimeter = 2(l+b)
34 cm = 2(x+x+3)
34 = 2(2x+3)
34 = 4x + 6
-4x = 6 - 34
-4x = - 28
4x = 28
X = 28 divided by 4 = 7
Breadth= 7 cm
Length = 7+3 = 10 cm
