Lera25 [3.4K]

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

Dakota built a wall with bricks like this one:
Viktor [21]
I have attached a screenshot with the complete question

Part (1):
We are given the prototype used for building the wall with the following dimensions:
long side = 8 in
short side = 5 in
Now, in the wall itself, we want to find the value of the length "a".
This length represents the short side in the prototype used in building the wall.
Therefore:
a = 5 in

Part (2):
We are given the prototype used for building the wall with the following dimensions:
long side = 8 in
short side = 5 in
Now, in the wall itself, we want to find the value of the length "b".
This length represents the long side in the prototype used in building the wall.
Therefore:
b = 8 in

Part (3):
Looking at Dakota's wall, we can note that its height is formed from three bricks each having the height "b". We have deduced previously that b = 8 in.
Therefore:
height of wall = 3 * b
height of wall = 3 * 8 = 24 in

Part (4):
Looking at Dakota's wall, we can note that its length is formed from nine bricks each having a length "a". We have deduced previously that a = 5 in.
Therefore:
length of wall = 9 * a
length of wall = 9 * 5 = 45 in

Hope this helps :)
