Question

Q1. Find the cost of leveling the ground in the form of a triangle having the sides 51 m, 37 m and 20 m at the rate of Rs 3 per m2 is Rs 918.
​

Answer 1

Answer:

Step-by-step explanation:

given , sides = 51 m

                       37 m

                         20 m

ATQ

area of triangle = √S(S−a)(S−b)(S−c)         s=a+b+c/2

                     = √54(54-51)(54-37)(54-20)     =51+37+20/2

                        =√ 54*3*17*34                         =108/2

                          =√  98838                                             =54

                      =314.3

ATQ  

the rate of Rs 3 per m 2 is Rs 918

then

314.3*3=Rs 943.15
