That would be an isosceles triangle.
square
it is called a isosceles shape if iT only has 2 sides that have the same exact length
The shape that has the same area and perimeter is a square with a specific side length. For a square with side length ( s ), the area is ( s^2 ) and the perimeter is ( 4s ). When you set these equal, ( s^2 = 4s ), and solving gives ( s = 4 ) or ( s = 0 ). Thus, a square with a side length of 4 units has both an area and perimeter of 16.

A four-sided shape with only 2 sides the same length is called a rhombus.
An isosceles triangle has 2 sides that are the same length and the other side does not match those other 2 side. For example, the measurements could be- 2 inches, 2 inches, and 5 inches.
isosceles triangle has two sides equal in length and two angles of the same measure;
(width side of the rectangle + length side of the rectangle) divided by 2
