Question

A farmer has a triangular field with sides 200m, 300m, 400m in which he grew wheat and in another triangular field with sides 200m, 320m, 360m, he grew vegetables, calculate the area of the land in which wheat and vegetables are produced? how can you motivate the students and make them aware about the use of both the food product mentioned above?

Answer 1

Answer 2

Answer:

Step-by-step explanation:

Wheat field

Sides :

a = 200 m

b = 300 m

c = 400 m

To Find area we will use heron's formula:

$Area = \sqrt{s(s-a)(s-b)(s-c)}$

where $s = \frac{a+b+c}{2}$

Where a,b ,c are the sides

Substitute the values

$s = \frac{200+300+400}{2}$

$s = 450$

$Area = \sqrt{450(450-200)(450-300)(450-400)}$

$Area =29047.375096 m^2$

Vegetable field

Sides :

a = 200 m

b = 320 m

c = 360 m

To Find area we will use heron's formula:

$Area = \sqrt{s(s-a)(s-b)(s-c)}$

where $s = \frac{a+b+c}{2}$

Where a,b ,c are the sides

Substitute the values

$s = \frac{200+320+260}{2}$

$s = 390$

$Area = \sqrt{390(390-200)(390-320)(390-360)}$

$Area =12474.3737 m^2$
