Question

the side of triangular plot are in the ratio 4:7:9 and perimeter 500m find its area ​

Answer 1

Answer:

8385.25 or 3750sqrt(5)

Step-by-step explanation:

4x + 7x + 9x = 500

x = 25

8385.25 or 3750sqrt(5)

area of triangle = sqrt(s(s-a)(s-b)(s-c)), where s = 500/2, a=100, b =175, c = 225

therefore, the answer is 8385.25 or 3750sqrt(5)
