Question

The length of rectangle is five meter more than twice of breadth if perimeter is 148 then find length and breadth

Answer 1

Answer:

length:39.5m

breadth :34.5

Step-by-step explanation:

let breadth be x and

length be x+5

perimeter : 2(l+b)

=2(x+x+5)

2(2x+5)

=4x+10 = 148

4x = 138

x=138/4

x=34.5

Answer 2

Answer:

Breadth of the rectangle=>x

length of the rectangle=>5+2x

Perimeter=>148(m or cm as per the unit given)

perimeter of the rectangle=>2(l+b)

To find b and l,

=>2(5+2x+x)=148

=>2×(5+3x)=148

=>10+6x=148

=>6x=148-10

=>6x=138

=>x=138/6

=>x=23

Therefore,

Breadth=>x=23

Length=>5+2x=5+2×23=51
