Question

Find the area of the triangular field with length of sides 360m , 450m ,and 450m by horan ' s formula

Answer 1

Answer:

Step-by-step explanation:

Herons formula=a+b+c/2

360+450+450/2

1260/2

630m

Answer 2

Answer:

a= 360m, b=450m, c= 450m

$s = \frac{a + b + c}{2} \\ s = \frac{360 + 450 + 450}{2} \\ s = \frac{1260}{2} = 630 \\ area \: of \: triagle = \sqrt{s(s - a)(s - b)(s - c)} \\ area = \sqrt{630 \times(630 - 360)(630 - 450)(630 - 450)} \\ area = \sqrt{630 \times 270 \times 180 \times 180} \\ area = 16200 \sqrt{21} m {}^{2}$
