Answer 2

ANSWER

d. 40 units

EXPLANATION

Method 1

Perimeter is the total distance around the figure.


The perimeter is


`= 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5`


`= 40 \: units`


Method 2

The three squares together formed a rectangle with dimensions,


`w = 5 \: and \: l = 15`





`Perimeter = 2w + 2l`



`Perimeter = 2(5) + 2(15)`


`Perimeter =10 + 30`



`Perimeter = 40 \: units`


The correct answer is D.
