He length of a rectangle is 15 cm more than its width. The perimeter is 150 cm. Findthe dimensions of the rectangle.​

Answer»

Answer:

Step-by-step explanation:

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 prooved
