Math Problem Statement

There's a square shaped field whose area is 121 meter^2. There's a rectangle shaped road along the diagonal of the field. If the breadth of the road is 1 meter. What's the area of the road?

Solution

The area of the square-shaped field is given as 121m2121 \, \text{m}^2. To find the area of the rectangular road along the diagonal of the square, we first need to find the length of the diagonal and then use the breadth of the road (which is 1 meter) to calculate the area.

Step 1: Find the side length of the square

The area AA of a square is related to the side length ss by the formula: A=s2A = s^2 Given that A=121m2A = 121 \, \text{m}^2, we can solve for ss: s=121=11ms = \sqrt{121} = 11 \, \text{m} So, the side length of the square is 11m11 \, \text{m}.

Step 2: Find the diagonal of the square

The diagonal dd of a square is related to the side length by the formula: d=s2d = s\sqrt{2} Substituting s=11ms = 11 \, \text{m}: d=112m11×1.414=15.556md = 11\sqrt{2} \, \text{m} \approx 11 \times 1.414 = 15.556 \, \text{m} So, the length of the diagonal is approximately 15.556m15.556 \, \text{m}.

Step 3: Calculate the area of the rectangular road

The area AroadA_{\text{road}} of the rectangular road is given by the product of its length (which is the diagonal of the square) and its breadth (which is 1m1 \, \text{m}): Aroad=d×breadth=15.556×1=15.556m2A_{\text{road}} = d \times \text{breadth} = 15.556 \times 1 = 15.556 \, \text{m}^2 Thus, the area of the road is approximately 15.556m215.556 \, \text{m}^2.

Final Answer:

The area of the road is approximately 15.56m215.56 \, \text{m}^2.
