Express the scenario as an inequality
First, we need to determine the number of hours Lauren can work.
This is calculated as follows:

From the question, we understand that the total hours cannot exceed 9 hours.
This can be expressed as 
So, we have:

Traditional 1/2 * base * height
Heron’s formula (it’s quite lengthy so search it up)
Hope this helped you :)
2d+4=10+2.5d
-2d -2d
4=10+0.5d
-10 -10
-6=0.5d
/0.5 /0.5
-12=d
d=-12
So the image consists of 1 rectangle and half a circle.
Rectangle - 12*19 = 228
Half a circle -

In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36
