Answer 2

Answer:

Option 3)

Step-by-step explanation:

let's divide the shape into three parts

S1- Horizontal line

S2- Small vertical line

S3- Horizontal line

area of S1=area of S3(having same measurements and same shape)

S1 area = L*B ( Area of a rectangle)

length=10cm

breadth=2cm

Area=20 cm (10X2)

Since S1 area = S2 add both the area = 20CM^2+ 20cm^2= 40cm^2

S3 is also a rectangle we will be using same formula but the measurements are changed so different area

Length=2

breadth=4

area= 2*4=8cm^2

adding all the area S1+S2+S3

40+8=48cm^2
