Trace needs a new carpet for her house the living are is an open floor plan of a dining room 6 feet c 4 feet sitting area 10 fee

hram777 [196]

Answer:

199 square feet

Step-by-step explanation:

Given:

Trace needs a new carpet for her house.

Dimension of dining room = 6 feet by 4 feet.

Dimension of sitting area = 10 feet by 15 feet.

Dimension of breakfast nook = 5 feet by 5 feet.

Question asked:

How many square feet of carpet does she need ?

Solution:

First of all we will calculate the area of each part of the house and then add up.

$Area \ of \ dining\ room=length\times width$

$=6\times4\\ \\ =24\ square\ feet$

$Area \ of \ sitting\ part=length\times width$

$=15\times10\\ \\ =150\ square\ feet$

$Area \ of \ breakfast\ nook=(side)^{2}$

$=5^{2} =25\ square\ feet$

Total carpet needed will be needed = For dining + For sitting area + For breakfast nook

= 24 + 150 + 25

= 199 square feet

Therefore, she needs 199 square feet of a new carpet for her house.

How is the number five and two hundred three thousandths written in standard form?

Andru [333]

Answer:

0.05203*10 to the power 2

Step-by-step explanation:

To get the standard form you divide a number in order to multiply it by a power of 10 to get the same number. So 5.203 in standard form is o.o5203 * 10 to the power 2. The 10 to the power 2 comes from the number of palces you move the comma/ decimal point to the left

It’s possible to build a triangle with side lengths of 5,5, and 10

nikitadnepr [17]

No. The two lengths 5 and 5 add up to 10; you'd have two sides of length 5 each placed end to end, equaling 10. That'd be represented by segments on a straight line, not a triangle.

Hope you've drawn a picture, so as to understand this better. ;)
