Draw a diagonal to divide it into two triangles; find the area of each triangle and add the answers.
A scalene triangle and a rectangle are two different shapes - a scalene triangle is a three-sided shape with no side lengths or angle sizes the same. A rectangle is a quadrilateral with four angles of 90 degrees.

A triangle can be proven congruent through four main criteria: Side-Side-Side (SSS), where all three sides of one triangle are equal to the corresponding sides of another; Side-Angle-Side (SAS), where two sides and the included angle of one triangle are equal to the corresponding parts of another; Angle-Side-Angle (ASA), where two angles and the included side are equal; and Angle-Angle-Side (AAS), where two angles and a non-included side are equal. Each of these criteria ensures that the triangles are identical in shape and size.
If a triangle does not have the same length side as another triangle the sides are not congruent.

An isosceles triangle is one of them
Yes its perpendicular height or altitude is sometimes calculated out side the triangle depending on its shape.
