Question

the length of a rectangle is 5 metre greater than its breadth if the perimeter of rectangle is 50 find its length ​

Answer 1

HEY MATE ! ✌✌

LET BREADTH OF RECTANGLE BE 'b'

THEN LENGTH = 5 + b

ATQ ,

2 (l + b) = 50

2 ( 5+b+b ) = 50

2 ( 5 + 2b ) = 50

10 + 4b = 50

4b = 50 - 10

b = 40 ÷ 4

b = 10

HENCE ,

LENGTH = 5+ b = 5+ 10

= 15 cm

BREADTH = 10 cm✅

Answer 2

Let length be x then breadth= x-5

Perimeter=2(l+b)

=>50=2(x+x-5)

=> 50/2=2x-5

=>25=2x-5

=>25+5=2x

=>30/2=x

=>15=x

Length=15
