Question

a triangle whose two sides are 60 cm and 100 cm with perimeter of 300 cm find the area with heron's formula​

Answer 1

HEYA USER ❤️

AB = 60 cm(a)

BC = 100 cm(b)

CA = ?

PERIMETER = AB+BC

+CA

300 = 60+100+CA

300=160 + CA

300-160=CA

CA = 140 cm(c)

NOW,

SEMI PERIMETER = PERIMETER/2

= 300/2

=150

BY USING HERON'S FORMULA,

Ar. = √[s(s-a)(s-b)(s-c)]

Ar. = √[150(150-60)(150-100)(150-140)]

Ar. = √[150×90×50×10]

Ar. = √[5×3×2×5×3×3×2×5×5×5×2×2×5]

Ar. = 5×3×2×5×5×2√3

Ar. = 750×2√3

Ar. = 2598.076 cm² ( required answer )
