Question
The perimeter of an isosceles triangle $A B C$, where the two equal sides each measure twice that of the base, is 60 units. Ifthe base of a similar triangle measures 6 units, then find its perimeter.
Step 1
Since the two equal sides each measure twice that of the base, the sides are $2x$ each. The perimeter of the triangle is the sum of all sides, so we have $x + 2x + 2x = 60$. Show more…
