Answer 1

Hi pupil here's your answer ::

_____________________________

✔Sides of triangular park are 15m 11m and 6m

☝a=15m b = 11m and c = 6m
☝s= 15+11+6/2
☝s=32/2
☝s=16

Area of triangle by HERON'S fromula

$\sqrt{s \: \times s - a \times s - b \: \times s - c}$
put the value

⏩root 16 (16-15) (16-11) (16-6)
⏩root 16×1×5×10
⏩root 4×4 ×1 ×5 ×5×2
⏩4×5 root 2 m sq

Hence, Area painted in colour of triangular park =
$20 \sqrt{2} \: {m}^{2}$
