In geometry, area is the amount of space a flat shape, like a polygon, circle or ellipse, takes up on a plane. The area of a shape is always measured in square units. Once you know how square units relate to area, you can find the area of just about any two-dimensional shape.In such a triangle, the legs are equal in length (as a hypotenuse always must be the longest of the right triangle sides): a=b a = b. One leg is a base, and the other is the height – there is a right angle between them. So the area of an isosceles right triangle is: \text {area}=\frac {a^2} {2} area = 2a2.Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side.
