The area of a rectangle is the space occupied within the boundary of the rectangle. It is calculated by finding the product of the length and breadth (width) of the rectangle and is expressed in square units.
Based on the measure of the internal angles, triangles are classified into three types: acute-angled triangle, right-angled triangle, an obtuse-angled triangle. Acute-angled Triangle If all the three angles in a triangle are acute angles, then the triangle is called an acute-angled triangle. ...
