Question

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

Answer 1

Option B

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.
