Answer 1

Answer:

triangular plot 145 .123 and is 14 and

Answer 2

Answer:

3√15m² and 54-3√15 m²

Step-by-step explanation:

Area of big plot= √s(s-a)(s-b)(s-c) = 54m²

Let sides of small triangle be 4x, 3x and 2x.

Then, x=2

Then sides are 8, 6 and 4

Then area for grass= 3√15

Area to be planted with trees= 54-3√15
