An architect designs a diagonal path across a rectangular patio. The path is 29 meters long. The width of the patio is [tex]x[/tex] meters, and the length of the patio is 5 meters more than the width.

Which equation can be used to find the dimensions of the patio?

A. [tex]0.5(x)(x+5)=29[/tex]
B. [tex]0.5(x)(x+5)=841[/tex]
C. [tex]x^2+(x+5)^2=29[/tex]
D. [tex]x^2+(x+5)^2=841[/tex]



Answer :

To solve the given problem of finding the correct equation that can be used to determine the dimensions of the patio, we need to break down the problem step-by-step and use geometric principles.

1. Identify Variables:
- Let's denote the width of the rectangular patio by [tex]\(x\)[/tex] meters.
- The length of the patio, being 5 meters more than the width, is [tex]\(x + 5\)[/tex] meters.

2. Determine the Relationship:
- The diagonal path across the patio forms the hypotenuse of a right triangle, where the width [tex]\(x\)[/tex] and the length [tex]\(x + 5\)[/tex] are the legs of the triangle.

3. Apply the Pythagorean Theorem:
- The Pythagorean theorem states that for a right triangle with legs [tex]\(a\)[/tex] and [tex]\(b\)[/tex], and hypotenuse [tex]\(c\)[/tex], the relationship is given by [tex]\(a^2 + b^2 = c^2\)[/tex].
- Here, the width [tex]\(x\)[/tex] and the length [tex]\(x + 5\)[/tex] are the legs, and the diagonal path of the patio, which is 29 meters, is the hypotenuse.

4. Formulate the Equation:
- According to the Pythagorean theorem:
[tex]\[ x^2 + (x + 5)^2 = 29^2 \][/tex]

5. Simplify the Right Side:
- Calculate [tex]\(29^2\)[/tex]:
[tex]\[ 29^2 = 841 \][/tex]

6. Write the Final Equation:
- Plugging in the value, the correct equation is:
[tex]\[ x^2 + (x + 5)^2 = 841 \][/tex]

So, the correct equation that can be used to find the dimensions of the patio is:
[tex]\[ x^2 + (x + 5)^2 = 841 \][/tex]
