The length of each side of a square increases by 40%. By what percent does the area of the square increase?

The area of the square increases by 96%

Step-by-step explanation:

Assume that the side of the square is x units

∵ The original side of the square = x

∵ The area of the square = side × side

∴ The original area of the square = x × x

∴ The original area of the square = x²

∵ The length of each side of a square increases by 40%

∴ The new side of the square = x + 40% × x

∴ The new side of the square = x + × x

∴ The new side of the square = x + 0.4x

∴ The new side of the square = 1.4x

→ Find the area of the new square

∴ The new area of the square = 1.4x × 1.4x

∴ The new area of the square = 1.96x²

→ Find the increase in the area

∵ The increase of area = new area - original area

∴ The increase of area = 1.96x² - x²

∴ The increase of area = 0.96x²

∵ The percentage of the increase = (increase ÷ original) × 100%

∴ The percentage of the increase in the area = × 100%

∴ The percentage of the increase in the area = 96%

∴ The area of the square increases by 96%

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
