▪The sides of a triangular plot are given in a ratio 16:8:10 and its perimeter is 340cm.its area in m^2 is 100. Find the value of using herons formula?

$\huge\boxed{\fcolorbox{white}{pink}{Answer}}$

☞Let the ratio be 16x:8x:10x

☞and it's perimeter =340 cm

Now, solution

☞ We know that sum of sides in triangle is called it's perimeter.

therefore.

☞16x+18x+10x=340cm

☞44x=340cm

☞x=340/44

☞x=7.27.

therefore

☞16x=16*7.72=123.52cm

☞18x=18*7.72=138.96cm

☞10x=10*7.72=77.2cm
