Answer:
Part a) The area of the actual floor is 
Part b) The ratio of the area in the drawing to the actual area is 
Step-by-step explanation:
we know that
The scale drawing is 
step 1
Find the dimensions of the square on a scale drawing
The area of a square is equal to

where
b is the length side of the square

so


step 2
Find the dimensions of the actual floor
Divide the length of the floor on the drawing by the scale drawing

step 3
Find the area of the actual floor
The area of a square is equal to

substitute

step 4
Find the ratio of the area in the drawing to the actual area

Simplify
Divide by 64 both numerator and denominator

Answer:
4:6 or 2:3
Step-by-step explanation:
Let me know if this is correct!
We know that
a) find <span>the ratio of the perimeters
</span><span>
the ratio of the perimeters is equal to the scale factor
</span>scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3
b) find <span>the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]</span>²*area smaller figure
scale factor²=area larger figure/area smaller figure
the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9
the answer Part b) is
169/9
the complete answer is
13/3 and 169/9
