Find the length of the side of the given square if area of the square is 625 square units and then find the value of x.

Solution:

Area of square = (side)²

Given, area of the square = 625 square units

As represented in the figure, side = (4x + 5)

∴ Area of square = (side)²

625 = (side)²

Side = √625 = 25 units

4x + 5 = 25

4x = 25 - 5

4x = 20

x = 5

✦ Try This: The area of the square of side (5x + 7)units is 1024 Sq units. Then find the value of ‘x’
