Split the followi

Answer :

The area of the above given figure can be calculated as:

(a)


We know that,


Area of rectangle = Length × Breadth


Therefore,


Atrea of 1st rectangle = 12 × 2 = 24 cm2


Also,


Area of 2nd rectangle = 8 × 2 = 16 cm2


Thereore,


Total area= 24 + 16 cm2


= 40 cm2


(b)

The area of the above given figure can be calculated as:


We know that,


Area of rectangle = Length × Breadth


Also,


Area of square = (Side)2


Therefore,


Area of one square = 7 × 7
= 49 cm2


As there are 5 squares in total of equal size.

Area of 5 squares = 5× 49 cm2
= 245 cm2

(c)

The area of the above given figure can be calculated as:


We know that,


Area of rectangle = Length × Breadth


Therefore,


Area of 1st recatngle = 5 × 1 = 5 cm2


Also,


Area of 2nd rectangle = 4 × 1 = 4 cm2


Therefore,


Total area = 5 + 4 = 9 cm2
