Answer 2

Answer:

1500√3

Step-by-step explanation:

ratio of sides = 3:5:7

so sides are 3/15* 300 = 60m,

5/15*300 = 100m & 7/15* 300 = 140m

semi perimeter

s = 300/2 = 150m

area = √[150(150-60)(150-100)(150-140)]

= √150× 90 × 50 × 10

= √ 5 × 3× 5 × 2 × 3 × 3 × 5 × 2 × 5 × 2 × 5 × 5 × 2

=125 × 3 × 4 × √3= 1500√3 m^2
