Question

The side of a triangular field are 51m, 37m and 20m. Find the number of rose beds that can be prepared on the field ,if each rose bed occupies a space of 6sq .m.

Answer 1

Answer:

Number of rose bed which can occupy the triangular field = 51

Step-by-step explanation:

Dimensions given- 51m, 37m, 20m

Area of triangle using three given sides = √s(s-a)(s-b)(s-c)

Here- a=51m, b=37m, c=20m

formula to calculate s = (a+b+c)/2

Hence- s = (51+37+20)/2 = 108/2 = 54

Area of triangular field = √54(54-51)(54-37)(54-20) = √54*3*17*34

                                       = √93636 = 306 sq. m

Area of 1 rose bed = 6 sq. m (Given)

Hence, number of rose bed which can occupy the triangular field

= 306/6 = 51
