The dimensions of a rectangular dining room are 18 feet by 16 feet. if a scale factor of 1/4 is used to make average scale model of the dining room, what is the area of the dining room in the scale model?
a: 18
b: 36
c: 48
d: 72

choice A, 18

Step-by-step explanation:

1/4 = 0.25

multiply 0.25 by each given dimension

18*0.25 = 4.5

16*0.25 = 4

The smaller scale model table is 4.5 feet by 4 feet, the area of which is

A = length*width = 4.5*4 = 18 square feet

note: it's a coincidence that we get a final result equal to one of the given values.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
