Area of UN-SHADED region is 10x + 25
Step-by-step explanation:
Both figures are squares
The area of un-shaded region is the difference between the areas of the larger square and the smaller square
The formula of the area of a square is A = s², where s is the length of its side
∵ The length of the side of the larger square = (x + 5)
- Find its area using the formula above
∴ Area of the larger square = (x + 5)²
∵ The length of the side of the smaller square = x
- Find its area using the formula above
∴ Area of the smaller square = x²
∵ The area of un-shaded region = Area larger - Area smaller
∴ The area of un-shaded region = (x + 5)² - x²
- Simplify it
∵ (x + 5)² = (x)² + 2(x)(5) + (5)²
∴ (x + 5)² = x² + 10x + 25
- Substitute it in the expression above
∴ The area of un-shaded region = x² + 10x + 25 - x²
- Add like terms
∴ The area of un-shaded region = 10x + 25
- Put A represents the area of un-shaded region
∴ A = 10x + 25
Area of UN-SHADED region is 10x + 25
