Answer:
First let us divide the shape into the rectangle which is the left part and the right angle triangle which is the right part.
For rectangle,
length=12
breadth=1
Therefore area of rectangle=l×b= 12×1= 12sq.cm
For right triangle,
First Arm=12cm
hypotenuse=13 cm
let the second arm be x
then by Pythagoras thereom,
x^2+12^2=13^2
x=√[169-144
x=√25
x=5cm.
So the area of triangle =(1/2)×h×b
where
height=12cm
base=5cm
therefore area of triangle=60/2 =30sq.cm
Since the shape was made up of rectangle and triangle
therefore,
Ar(shape)=Ar(rectangle)+Ar(Triangle)
12+30
42 sq.cm
