Question

the side of a square (5 a - 2b )find its area

Answer 1

Hey there!

Answer : 25a² + 4b² - 20ab.

Explanation :

We know that,

Area of a square = side × side = side²

Given,

Side of a square = ( 5a - 2b)

Area = ( 5a -2b)² = 25a² + 4b² - 20ab.

We have used the identity,
( a - b) ² = a² + b² - 2ab

Therefore,

Area of the square is 25a² + 4b² - 20ab.
