Question

Find the area of whose sides are 60 cm, 153 cm and 111 cm.​

Answer 1

As you didn't mentioned the shape..

so I hope it's a tri angle

and then as per the formula the area will be

√s(s-a)(s-b)(s-c) where s is the half of its parameter.

so

the parameter of this triangle is-(60+111+153)cm

= 324cm

and half of the parameter is- 324/2cm= 162cm

now the area will be-

√162 (162-60)(162-111)(162-153)cm²

=√162×102×51×9cm²

=√3×17×3×3×3×2×1×2×1cm²

=3×3×2√17cm²

= 18√17cm2
