Answer 1

Answer:

Step-by-step explanation:

This is simple: we need to only do 2 steps

1) Convert to feet

2) Get the area

1) Converting to feet is just

$(7*3, 4*3)$ (ignore the use of this it's just to show the differnt things to multiply

Now we have a length of 21 and a width of 12 FEET.

2) To solve for the area, we need to multiply both dimensions.

$21*12=252$

So the answer is 252^2 FEET (DONT FORGET THE UNIT SQUARE FEET)
