Question

Suresh took 15 seconds to cross a rectangular field diagonally walking at the rate of 52 m/min,

and Rajesh took the same time to cross the same field along its sides walking at the rate of 68

m/min. Find the area of the field.​

Answer 1

Answer:

the area of rectangular field is 11m.

Step-by-step explanation:

As suresh travelled alone Dia so distance covered is speeding into time. (52/60×15=13m)

As Rajesh travelled along side so distance covered is speeding into time (68/60×15=17m)

so by law of triangle we have given two sides so we can find third one

Answer 2

Answer:

 

Step-by-step explanation:

length of diagonal =13 m

2(L+B) = 17 m ------- (1)

L²+B² = 13² ----------(2)

SOLVING BOTH 1 AND 2

2L²- 17L = 387/4

on solving quadratic equation we will get value of L and B
