Actually Welcome to the Concept of the Area and Volumes.

First we divide this figure in to two shapes , that are Triangle and Rectangle and apply their area formulae.

Total Area = Area of triangle + Area of Rectangle.

Area of triangle = 0.5*b*h

= 0.5*4*5

= 10 sq. units.

---> Area of Rectangle = l*b

= 7*5= 35 sq. units

thus the total area of the Shape is

= 35 + 10= 45 sq. units
