If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.

An isosceles triangle is a triangle with two equal sides. To find the perimeter of the triangle, you simply need to add together the lengths of the base and the two sides. So: 3.9 + 4.6 +4.6 = 13.1 inches.

assuming its an isosceles triangle, then its 16 cm high

By using Pythagoras' theorem.

It is a trapezoid in which the non-parallel sides are of the same length and subtend equal angles with the base. It can be viewed as an isosceles triangle whose apex has been removed by a line parallel to its base.

If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.

Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.

That's not enough information to solve the problem.

If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.

Perimeter = 10 + 10 + 12 = 32 units. Area = 48 square units

The two sides are each 3086 centimeters in length. An isosceles triangle has a base and two congruent sides. If the base of an isosceles triangle is 43 cm long and the perimeter of that triangle is 6215 cm, then the length of the two congruent sides is 6215 cm minus 43 cm, or 6172 cm. Each side will be half that, or 6172 cm divided by 2, or 3086 cm.

Lengths of: equal side+equal side+base = perimeter

In effect what you are asking is "does 5 + 5 + 5 = 6 + 6 + 3?" which of course it does. Is it the word perimeter that caused confusion?

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

Yes 5+5+5 = 15 6+6+3 = 15

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.

Perimeter = 81+81+29 = 191 units of measurement
