Circumference 7065

In an isosceles triangle, the base length is equal to 75% of the arm's length. If the circumference is 22 cm, determine the area of the triangle.

Final Answer:

S =  22.2486 cm2

Step-by-step explanation:

o=22 cm q=75%=10075=43=0.75  z = q   r o = 2r + z o = 2r + q r  r=o/(2+q)=22/(2+0.75)=8 cm  z=q r=0.75 8=6 cm h=r2(z/2)2=82(6/2)2=55 cm7.4162 cm  S=2z h=26 7.4162=3 55=22.2486 cm2
