Question

Three identical squares of length 1 cm are pasted in a rectangle of length 6 cm and breadth 5 cm as shown below . What is the area of the figure formed ? Options : 1. 29 cm 2. 30 cm 3. 31 cm 4. 33 cm

Answer 1

Step-by-step explanation:

Let the side of each square be x.

So, perimeter of figure P = 12x

⇒240=12x⇒x=20cm

∴ Perimeter of figure Q = 10x

= 10×20=200cm

Answer 2

Step-by-step explanation:

$area \: of \: rectangle = l \times b$

Therefore ,

L = 6cm

B =5cm

area = 30cm²

area of Figure obtained = 30-2+1

= 29cm²
