Raj runs in a park which is in a shape of rectangle, he completes one lap and then he runs across the diagonal of the park. The dimensions of the park are 100 m × 120 m. What is the total distance travelled by him diagonally?(a) 156.2(b) 200(c) 1000(d) 75This question was posed to me during an interview for a job.Origin of the question is Quadrilaterals in section Quadrilaterals of Mathematics – Class 8

Answer»

Correct answer is (a) 156.2

For EXPLANATION I WOULD say: We know that all the angles subtended by the sides of a rectangle are 90° in measure. THEREFORE we can USE Pythagoras theorem to FIND the distance travelled by Raj diagonally.

(100)^2 + (120)^2 = x^2

X = 156.2 m.
