the length of each leg is more than 4..
the answer would be 22.5
Pyramids are not isosceles triangles but their triangular faces can form the image of an isosceles triangle if they have two sides of equal lengths and a base of a different length.
Information about the base length is not enough to determine the lengths of the legs other than that they must be more than 5 units.
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
They are of the same lengths
The base angles of an isosceles triangle are congruent.

Any length greater than 3 inches.

Lengths of: equal side+equal side+base = perimeter
When you double the length of one side, the area is increased by a factor of four. Example:A square with side lengths of 10 feet has an area of 100 square feet.A square with side lengths of 20 feet has an area of 400 square feet.
The side that is not the same length as the other two sides.
The base angles of an isosceles triangle are congruent.
Providing you know the length of its base and the lengths of its two equal sides, treat it as being two right angled triangles joined together by halving the length of its base. Then use Pythagoras' theorem to find its height.
