Answer 1

Here is your answer... I hope I solved your problem so please mark as brainly.

Answer 2

Here is your solution

Given:-

Sides Of a Triangular Field are 50 , 45, 35, metre.

Let,
First Side = a
Second Side = b
Third Side = c

We know that

Semiperimeter = a+b+c/2

=> 50+45+35/2

=> 50+80/2

=> 130/2

=> 65

Hence semiperimeter is 65

Using Heron's Formula

Area = √s(s-a)(s-b)(s-c)

=> √65(65-50)(65-45)(65-35)

=> √65(15)(20)(30)

=> √ 585000

=> 764.85 m²

Now, we have to find
Required number of flower beds that can be prepared if each bed measures 5m²


=> 764.85m² /5m²

=> 152.97

153(approx)

Hence,
Required Number of flower beds = 153

Hope it helps you
