Answer:

Needed length of board for ramp = 13 feet

will the board be long enough? = No, this board is not long enough

Step-by-step explanation:

Step 1: Draw an illustration representing the porch, the sidewalk, and the distance of the sidewalk to the base of the porch.

Step 2: use the Phytagorean Theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Substitute

25 + 144 = [tex]c^{2}[/tex]

Add

25 + 144 = [tex]\sqrt{169}[/tex] or 13 feet

Conclusion

13 feet > [tex]12\frac{3}{4}[/tex]
