ISO Triangle V2

The perimeter of RR triangle (isosceles) is 474 m, and the base is 48 m longer than the arms. Calculate the area of this triangle.

Correct answer:

S =  10026.4 m2

Step-by-step explanation:

474=2a+b b=a+48  474=3a+48 a=142 b=a+48=190  h2=a2(b/2)2 h=1422(190/2)2 h=105.541  S=bh2=190105.5412 S=10026.4 m2
