The area of the figure shown below is 150
What is area?
The size of a region on a surface is expressed in terms of area. Whereas surface area refers to the area of an open surface or the edge of a three-dimensional object, area of a plane region or plane area refers to the area of a form or planar lamina. The area of the figure can be seen as the sum of are of square and area of triangle.
The are of square =

Where a =10
The area of square = 10*10=100
The area of the triangle=

where b= base =10
h= height=10
The area of the triangle=
=50
The total area = 100+50 = 150
