Question

length =20mmore than its breath and breadth=x perimeter of floor=280m the length = ?​

Answer 1

length= 20+x

breadth=x

perimeter of floor=280m

perimeter of floor=2(length+breadth)

= 280= 2(20+x+x)

= 280 = 2( 20+2x )

=280 = 40 + 4x

=280 - 40 = 4x

= x = 240 / 4

= x= 60

.

.

. thus

length= 20+x = 20+ 60 = 80m   (  answer  )

and

breadth=x = 60m
