Question

Find the area of a triangle whose sides are 40 metre, 24 meta and 32 metre .

Answer 1

Semi perimeter = $\frac{40 + 24 + 32}{2}$

Semi perimeter = 96/2 = 48
___________________

Area by Heron's Formula 

Area = $\sqrt{48 (48-40) (48-32)(48-24)}$

Area = $\sqrt{48 * 8 * 16 * 24}$

Area = $\sqrt{147456}$

Area = 384 m^2




i hope this will help you
