Calculating the Total Bill

1. Sandwiches: 3 × 250 = Rs. 750

2. Cold drinks: 2 × 180 = Rs. 360

3. Coffee: Rs. 210

4. Total food cost: 750 + 360 + 210 = Rs. 1320

5. Tax: Rs. 112

6. Total bill: 1320 + 112 = Rs. 1432

Change Calculation

Amount paid: Rs. 5000

Change = 5000 - 1432 = Rs. 3568

Explanation

To factorize the quadratic expression x² - 12x + 35, we need to find two numbers whose product is 35 and whose sum is -12.

The numbers are -7 and -5, since (-7) * (-5) = 35 and (-7) + (-5) = -12.

So, the factorization is:

x² - 12x + 35 = (x - 7)(x - 5)

Explanation

To find the area of the road, we need to find the area of the garden and subtract the area of the inner garden (without the road).

Garden area = Length * Width

= 75 cm * 82 cm

= 6150 cm²

Inner garden dimensions:

Length = 75 cm - 2 * 5 cm = 65 cm

Width = 82 cm - 2 * 5 cm = 72 cm

Inner garden area = 65 cm * 72 cm

= 4680 cm²

Road area = Garden area - Inner garden area

= 6150 cm² - 4680 cm²

= 1470 cm²
