Answer 2

Answer:

Area of the village hall = 30.25 sq. km

We know, area is given as,

Area = (side)²

⇒ 30.25 = (side)²

⇒ side = √[30.25] = 5.5 sq. km

Here we asked to find the dimension of the longest side of the triangle. Since the hall is divided into 2 triangles of equal area, therefore, it is given by finding the value of the diagonal of the hall i.e.,

Diagonal = side * √[2] = 5.5√2 km or 7.7 km(= 5.5*1.414)

Thus, the dimension of the longest side of the triangle is 5.5√2 km or 7.7 km.
