Question

the lenght of rectangular hall is 5 metres more than its breadth.if the perimeter of the hall is 74 metres find its lenght and breadth.

Answer 1

Answer:

breadth=16 m lenght=21 m

Step-by-step explanation:

let the lenght be x + 5 and the breadth be x then

perimeter =74

perimeter =2(l+b)

so,

2(l+b)=74

2(x+5+x)=74

2*(2x+5)=74

4x+10=74

4x=64

x=64/4

=16

Answer 2

Answer:

this is your answer

Step-by-step explanation:

let lenght be = b+5 , where b =  breath

then,

2[b+5+b]=74

2[2b+5]=74

4b+10=74

4b=64

b=64/4

b=16

breadth=16

lenght=16+5=21.

hence proved...
