Question

One side of a rectangle is 4 centimetres longer than the other side and its area is 896 square centimetres. What are the lengths of the sides?​

Answer 1

Answer:

28

Step-by-step explanation:

Given,

Let one side be x cm,

then, the other side will be x+4 cm.

According to the problem,

x*(x+4)=896

or, x^2+4x=896

or, x^2+4x-896=0

or,x^2+32x-28x-896=0

or,x(x+32)-28(x+32)=0

or,(x+32)(x-28)=0

therefore, x=28
