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.
<u>Question asked:</u>
How many square feet of carpet does she need ?
<u>Solution:</u>
<em>First of all we will calculate the area of each part of the house and then add up.</em>
<em />
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.

Answer:
Perimeter of sector is 47.93 cm which is greater than 47.5 cm
Step-by-step explanation:
Mathematically, the perimeter of a sector is length of the arc plus 2 radii
The length of the arc is;
theta/360 * 2 * pi * r
where theta is the angle subtended by the arc at the center of the circle
Thus, we have
135/360 * 2 * 22/7 * 11 = 25.93
Add 2 radii = 25.93 + 2(11) = 47.93 cm
This is greater than what we are asked to calculate and thus we have shown what we are asked to show
