The scale drawing of a living room has an
indicated length of 10 cm and height of 8 cm
inches. The scale in drawing is 1 cm: 12.5
feet. What are the length and width of the
actual room? Find the area of the actual room.

We are given that one centimeter represents 12.5 feet. Thus, the dimensions in centimeters of the scale drawing will be 12.5 times larger in feet for the actual room.

Multiply 10 cm with 12.5 to get the length of the room in feet.

The length of the room is 125 feet. Multiply 8 cm with 12.5 to get the width of the room in feet.

The width of the room is 100 feet. Now, we multiply the length with the width to get the area of the room.

The area of the room is 12,500 feet squared. Let me know if you need any clarifications, thanks!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
