Question

cost of chair is (x + y). if rahmi bought (x + y) chairs then find the totol amount paid by using suitable idenity

Answer 1

Step-by-step explanation:

Cost of each chair = (x+y)

Number of chairs bought = (x+y)

Hence,

Total amount paid = (x+y)(x+y) = (x+y)²

= x² + 2xy + y²

Answer 2

Given:

• Cost of chair is (x + y)
• Rahmi bought (x +y)

To Find:

• Total amount paid by using suitable identity

Solution:

Total amount paid by using suitable = (x +y)(x+y) = (x+y)^2

= x^2 + y^2 + 2xy
