Answer:
4
Step-by-step explanation:
The area, a of the room is 8* 5.5
a = 44 sqaure feet
one square foot of tiles are sold in packages of 12
To get the number of packages needed, simply divide the area of the room by 12
This gives:
44/12 = 4
= 3.67 round up to the nearest whole number
= 4

divide
Answer:
a=9.4 b=12.0
Step-by-step explanation:
You need to use Pythagorus
So for a:
8²+5²=89 a=√89=9.4
And b:
17²-12²=145 b=√145=12.0
see the picture in the attached figure
step 1
find the area of rectangle
A=110*43
A=4730 yd²
step 2
find the area of semicircles
we know that two semicircles is equal to one circle
so
Area of the circle=pi*r²
r=43/2
r=21.5 yd
A=pi*21.5²
A=462.25 *pi yd²-------->1,451.465 yd²
total area=area rectangle + area of circle
total area=4,730+1,451.465---------> 6,181.465 yd²
step 3
find the cost
$0.12 per square yard
6,181.465*0.12=$741.78
therefore
the answer is
$741.78
