Question

If each grey square is 1cm in width and length, then what is the area of the shape? 

Answer 1

The options for this question are missing. here are the missing options:

A.22cm²

B.13cm²

C.15cm²

D.12cm²

Answer

First of all we will find the area a^2= area of square = a(a)  

We already know that a = 1 cm

area of 1 block = 1 (1) =1 cm^2

as the area of each block is 1 cm^2  

the area of 15 blocks = 1 cm^2 (15) (there are total of 15 blocks)

So the option C is the correct answer.
