Question

The length of a rectangle is 15 cm greater than its breath. Its perimeter is 150cm. Find the dimension of the rectangle​

Answer 1

Answer:

45 cm

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

Verification:

150 = 2( 45+30)

150 = 2(75)

150 = 150
