1. Calculate the area of the smaller patio: 15 \times 20 = 300 \text{ ft}^2
2. Calculate the area of the larger patio: 19 \times 26 = 494 \text{ ft}^2
3. Set up a proportion comparing the two patios:
\frac{300 \text{ ft}^2}{2275} = \frac{494 \text{ ft}^2}{x}
4. Solve for \( x \):
x = \frac{494 \times 2275}{300}
5. Compute \( x \):
x\approx3746.17
6. Therefore, the estimated cost for the 19' x 26' patio is:
3746.17
