Answer:
420√ 5
Step-by-step explanation:
Sides:
a= 35cm, b = 54cm, c = 61cm
Perimeter = Sum of all sides
= 35 + 54 + 61
= 150 cm
Semi Perimeter (s) = Perimeter/2 = 150/2
=> 75 cm
s - a = 75 - 35 => 40
s - b = 75 - 54 => 21
s - c => 75 - 61 => 14
Area = √ s(s-a)(s-b)(s-c)
= √ 75 × 40 × 21 × 14
= 420√5
