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

If i have a pay rate of $21.00 and marked up 78.7% and made a 10% profit. how did i get $41.28?
Feliz [49]

Answer:By multiplying with (1+0.01x) where x is the percentage of increase, monthly pay rate of 21$ after marked up 78.7% and 10% profit will be $41.28.

Step-by-step explanation:

Given that pay rate is 21$ and it is marked up by 78.7% and made a 10% profit.

If any value marked up or made a profit of x% then we have to multiply with (1+0.01x) to find the new value.

New pay after 78.7% marked up using above formula is 21X(1+0.01X78.7)=21X1.787=37.527

Now we have to use above formula again for 10% profit.

Hence new value =37.527(1+0.01X10)=37.527X1.1=41.2797≈$41.28
