ISO triangle

Calculate the area of an isosceles triangle KLM if its sides' length is in the ratio k:l:m = 4:4:3 and has a perimeter 377 mm.

Correct answer:

S =  6533.4 mm2

Step-by-step explanation:

k=l=4+4+34377=137.091 mm m=4+4+33377=102.818 mm  h2=k2(m/2)2 h=137.091251.4092=127.087 mm  S=21mh=21102.818127.087=6533.4 mm2
