1.	the width of a rectangle is 25 cm and its length is 45 cm. what is the ratio of the width to the perimeter?
Answer» Answer: LET the breadth=x the length =x+15 given perimeter=150 we KNOW Perimeter of rectangle=2(l+b) 150 = 2( x+ x+15) 75=2x+15 60=2x 30=x therefore breadth =30 cm length =30+15=45 cm check 150=2(45+30) 150=2(75) 150=150 LHS=RHS hence PROVED.

the width of a rectangle is 25 cm and its length is 45 cm. what is the ratio of the width to the perimeter?

Answer»

Answer:

LET the breadth=x

the length =x+15

given perimeter=150

Perimeter of rectangle=2(l+b)

150 = 2( x+ x+15)

75=2x+15

60=2x

therefore breadth =30 cm

length =30+15=45 cm

check

150=2(45+30)

150=2(75)

150=150

LHS=RHS

hence PROVED.
