Question

The area of a square floor on a scale drawing is 25 square centimeters, and the scale drawing is 1 centimeter:5 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?

Answer 1

Answer:

$625ft^{2}$

Step-by-step explanation:

First get the l by finding the square root of the area

$\sqrt{25}$ = 5cm

since             1cm = 5ft

what about   5cm =?

(5cm×5ft)/1cm

l=25ft

area of the actual floor is l × l

$25^{2}$

which is $625ft^{2}$
