please answer tell me gyz and explanation this question​

Answer 1

Answer:

2598.07 m².

Step-by-step explanation:

Let the sides be 3s, 5s and 7s. ATQ,

3s + 5s + 7s = 300

15s = 300

s = 20.

So the sides are 3(20), 5(20) and 7(20) or 60 m, 100 m and 140 m.

s = 150 m, a = 60 m, b = 100 m, c = 140 m.

Area = √{s(s - a)(s - b)(s - c)}

√(150 * 90 * 50 * 10)

√6750000

2598.07 m².

So the area of the land is 2598.07 m².

Hope it helps, pls mark it as the BRAINLIEST and pls follow me! :):)

Answer 2

Answer:

answer is 60 100 140

Step-by-step explanation:

3:5:7=300

3x+5x+7x=300

15x= 300

X=20

so the area of the land is 3x=3*20=60

5x=5*20=100

7x=7*20=140
