To find the area of a triangle, we can use the formula:

\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]

Step 1: Calculate the area of the first triangular sign.

For the first sign:

  • Height = 3 feet
  • Base = 2.5 feet

Using the area formula:

\[ \text{Area}_1 = \frac{1}{2} \times 2.5 \times 3 \]

Calculating this:

\[ \text{Area}_1 = \frac{1}{2} \times 7.5 = 3.75 \text{ square feet} \]

Step 2: Calculate the area of the second triangular sign.

For the second sign:

  • Height = 2.5 feet
  • Base = 3 feet

Using the area formula:

\[ \text{Area}_2 = \frac{1}{2} \times 3 \times 2.5 \]

Calculating this:

\[ \text{Area}_2 = \frac{1}{2} \times 7.5 = 3.75 \text{ square feet} \]

Step 3: Compare the areas.

Now we have both areas:

  • \(\text{Area}_1 = 3.75\) square feet
  • \(\text{Area}_2 = 3.75\) square feet

Step 4: Calculate the difference in area.

Now we calculate how much larger the first area is compared to the second area:

\[ \text{Difference} = \text{Area}_1 - \text{Area}_2 = 3.75 - 3.75 = 0 \]

Conclusion

The first triangular sign is not larger than the second sign; both signs have the same area of 3.75 square feet.
