Answer:
B
Step-by-step explanation:
The area is calculated by length×width. In this case you don't know the length or width precisely so you say 2w (squared) because it's the width×width and you subtract 19 because then you actually have width×length.
You just have to multiply 48 by 4 to find out its original price
Using Pythagoras theorem :
C = sqrt(a^2 + b^2)
C = sqrt(36+64)
C = sqrt(100)
C = 10 feet
You can use ten blocks to find 2.16/3 by using 7 base ten blocks and two base one blocks
