hope it helps

Step-by-step explanation:

Let a = 41m, b = 40 m, c = 9 m.

s = (a + b + c)/2 = (41 + 40 +9)/2 = 90/2

⇒ s = 45 m

Area of the triangular field = root under(√s(s – a)(s – b)(s –c))

= root under(√45(45 – 41)(45 – 40)(45 - 9))

= root under(√45 x 4 x 5 x 36 ) = 180 m2 = 1800000 cm2

Number of rose beds = Total area / Area needed for one rose bed

= 1800000/900 = 2000
