Answer:

2595m2

Step-by-step explanation:

let the sides of the triangular plot be 3x,5x and 7x

=3x+5x+7x=300

15x=300

x=20

therefore the side of the plot are

3x=3(20)=60m

5x=5(20)=100m

7x=7(20)=140m

Now,let a=60;b=100;c=140

s=60+100+140/2=150m

Area of plot=✓s(s-a)(s-b)(s-c)

✓150(150-60)(150-100)(159-140)

✓150x90x50x10

✓15x10x9xx10x5x10x10

10x10x3✓15x5

300✓3x5x5

300x5✓3

1500✓3m2

1500x1.73

2595m2
