Question

If the triangle having base 50 cm, perpendicular height is 100 cm and hypotaneous 110 cm then what is the area of triangle?

Answer 1

Answer:

Perimeter= 110 + 50 + 100

= 260

2s = 260

s = 260/2

= 130

Heron's Formula = √ s(s-a)(s-b)(s-c)

= √ 130 (130-110) (130-50) (130-100)

= √ 130×20×80×30

= √ 13×10×2×10×2×2×2×10×3×10

= 10×2×2×10 √13×3

= 400√39
