Question

The length of rectangular room is
(x+y) and breadth is (x-y) units
and the area of the room is 200
square feet. Weite the quadratic equation.​

Answer 1

Answer:

x^2-y^2 = 200

Step-by-step explanation:

area of rectangle = length×breadth

200 = (x+y) × (x-y)

200 = x^2-xy+yx-y^2

200 = x^2-y^2

the quadratic equation is,

x^2-y^2 = 200
