Question

the side of the triangular plot are in the ratio 3:5:7 and its perimeter is 300m find its area​

Answer 1

Step-by-step explanation:

3x + 5x + 7x = 300

x = 300/15

Thus x = 20

3× 20 = 60

5 × 20 = 100

7× 20 = 140

(a + b + c) /2. = s

300/2 = 150

√s × s-a × s-b × s-c

√150 (150-60) (150-100) (150-140)

√150 × 90 × 50 × 10

Thus 1500√3m²
