You want to produce a scale drawing of your living room, which is 21 ft by 28 ft. If you use a scale of 5 in. = 7 ft, what will be the dimensions of your scale drawing?

Answers

Answer 1
Answer:

Answer:

15 in. by 20 in.

Step-by-step explanation:

Dimensions of living room :

Length = 21 feet

Width = 28 feet

Scale : 5 in. = 7 ft

So, 1 ft. = (5)/(7) in.

So, 21 feet = 21 * (5)/(7) in.

21 feet = 15 inches

Now 28 feet = 28 * (5)/(7) in.

28 feet = 20 inches

So, the dimensions of the scale drawing = 15 in. by 20 in.

Hence the dimensions of the scale drawing is 15 in. by 20 in.                                                      

Answer 2
Answer: 5 in --------- 7 ft
x in  --------- 21 ft

x = (5 x 21)/7=15 in

Otherwise:

5 in ---------- 7 ft
x in  ---------- 28 ft

x = (5 x 28)/7 = 20 in

Dimentions of drawing is 15 x 20 in

The clearance sale advertised 1/3 off the list price of clothes and 1/2 off the list price of luggage. Ramon bought a suitcase with a list price of $100 and a coat with a list price of $195. What was his total bill?A. $115
B. $150
C. $180
D. $295

Answers

The closest answer C, however the actual answer is $196.25. 
price of the coat = 2/3*195 = 2*195/3 = 2*65 = 130
price of the luggage = 1/2*100 = 100/2 = 50
total bill = 130+50 = 180

A rectangle has a perimeter of 238 meters and a length of 67 meters what is the area of the rectangle

Answers

Answer:

3,484 meters squared

Step-by-step explanation:

Since it’s a rectangle, opposite sides are the same length. This means 2 of the sides are 67 meters each, since the length of the rectangle is 67 meters. To find the width, add the 2 sides together that we know the length of (in this case it would be 67+67) and subtract it from the total perimeter (238-[67+67]). Take the result (104) and divide it by 2 (104÷2=52). Now that we know the width is 52 meters, you can find the area by multiplying the length times the width (67*52=3,484 meters)

Remember that the perimeter is the total length around the outside of the shape, and the area is the space inside of the shape
