Part 1) <span>Create a diagram that shows Kamila’s rectangular lawn and the gravel border. Assign variables to any unknown sides and label the diagram
see the attached figure
Part 2)</span><span>Use your diagram to determine how many square feet of the gravel border will surround the lawn
area of the border=[162*92]-[150*80]----> 14904-12000-----> 2904 ft</span>²
Part 3) <span>Kamila decided that the depth of the gravel needs to be 2 inches. What is the total volume of gravel needed for the border?
we know that
1 ft-------> 12 in
x--------> 2 in
x=2/12------> x=0.17 ft
volume of gravel needed=area of the border*deep of the gravel
</span>volume of gravel needed=2904*0.17----> 493.68 ft³
<span>
Part 4)</span><span>A large bag of colored rock contains a cubic yard and costs $30. What is the total cost of the rocks needed for the border?
</span>
1 yd³--------> 27 ft³
x---------> 493.68 ft³
x=493.68/27-----> 18.28 yd³
if 1 yd³----------> cost $30
18.28 yd³------> x
x=18.28*30------> x=$548.53
the answer Part 4) is
$548.53
