168 km². Area of rectangle = Length*Breadth = 13*7 = 91 km² Area of triangle = 1/2*Base*Height = 1/2*14*11 = 77 km² Area of figure = Area of rectangle + Area of triangle = 91+77 = 168 km²

It is formed by the diagonal of a rectangle

The area of a rectangle is length times width, so 7 km times 13 km is 91 square km. Now the area of a triangle is 1/2 base times height. We'll take 14 times 11 and get 154. Divide this now by 2 to get that the area of our triangle is 77 square km. Now we just need to add 91 and 77 to get an answer of 168 square km.

A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.Example 20Find the area of the following composite figure:Solution:The figure can be divided into a rectangle and triangle as shown below.So, the area of the composite figure is 216 cm2.

It is a plane figure, for example, a semicircle, a triangle, a kite.
