When the length of the base of an isosceles triangle is one third the length of one of its legs the perimeter of the triangle is 62 inches what is the length of the base?

OK, so let's say the length of the base = x. The leg length = 3x, as it's three times the base length. As there are two legs and a base making up the perimeter, the perimeter = 10x. So 62 = 10x. 62/10 = 6.2, therefore x = 6.2 and the base = 6.2 inches.
Hope this helps!
If base = x and each leg = 3x, then the perimeter would be 7x instead of 10x as mentioned above. (3x + 3x +x = 7x). Hence, perimeter = 7x and the base (x) = 8.857 inches.

If Each leg of an isosceles triangle is 9 inches longer than one half the length of the base. If the perimeter of the isosceles triangle is 146 inches what is the length of one leg of the isosceles t?
Let the base length be x:- If: 2(0.5x+9)+x = 146 => x+18+x = 146 => 2x = 146-18 => x = 64 Therefore the isosceles triangle has 2 equal sides of 41 inches and a base of 64 inches Check: 41+41+64 = 146 inches

What is the perimeter of an equilateral triangle that measure 4 in on one side?
The perimeter of an equilateral triangle with a side length of 4 inches is 12 inches. Each side of an equilateral triangle is equal in length, so the perimeter is found by multiplying the side length (4 inches) by 3.
How do you find a perimeter of an isosceles triangle?
