Question

Find the area of the shaded region and choose the appropriate result?

Answer 1

Answer:

Option B

Step-by-step explanation:

The figures are made out of squares.

$\text {Formula for area of a square: } A =s^2\\s-\text {Length of side.}$

Square 1 (the gray square):

The side measure is 4 cm.

$A = 4^2 = 16cm^2$

Square 2 (white square):

The side measure is 2 cm.

$A=2^2=4cm^2$

Subtract the area of the white square from the gray square to get the area of the shaded region:

$16 - 4 =12$

The shaded region is $12cm^2$.

Option B should be the correct answer.
