Question

siin. The scale used for a model of a kitchen isdimensions of the kitchen?1ft. In the model, the kitchen measures $2in. by 3 in.

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

Model

1 / 4 in = 1 1/2 ft

dimensions of the kitchen

2 1/2 in by 3 in

Step 02:

$1\text{ }\frac{1}{2}\text{ ft = 1 + }\frac{1}{2}\text{ = }\frac{2+1}{2}=\frac{3}{2}\text{ ft}$$2\text{ }\frac{1}{2}in\text{ = 2 +}\frac{1}{2}\text{ = }\frac{4+1}{2}\text{ =}\frac{5}{2}in$

Step 03:

1 / 4 in = 3 / 2 ft

$\frac{5}{2}in\cdot\text{ }\frac{3\text{ / 2 ft}}{1\text{ /4 in }}\text{ = }\frac{5\text{ }}{2\text{ }}in\cdot\text{ }\frac{3\cdot4\text{ ft}}{2\cdot1\text{ in}}$$\frac{5}{2}in\cdot\text{ }\frac{12ft}{2in}\text{ = }\frac{5\cdot12\text{ }}{2\cdot2}=\text{ }15ft$$3\text{ in }\cdot\text{ }\frac{12ft}{2in}\text{ = }\frac{3\cdot12}{2}=18ft$

The answer is:

b. 15 ft by 18 ft
