The length of the rectangular field is 120 ft if the width of a rectangular field is 20 feet less than its length and the area of the field is 12,000 ft².
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let's suppose the length of the rectangular field is l and the width is w.
w = l - 20
The area of the rectangular field
lw = 12000
l(l - 20) = 12000
l² - 20l - 12000 = 0
After solving the quadratic equation, we get:
l = 120 or l = -100(length cannot be negative)
Thus, the length of the rectangular field is 120 ft if the width of a rectangular field is 20 feet less than its length and the area of the field is 12,000 ft².

Answer: 36 hours
Step-by-step explanation:
t = total hours

t = 5(4) + 8(2)
t = 20 + 16
t = 36
Answer:
38 and 108
Step-by-step explanation:
2a + 6b
2 (4) + 6 (5) Plug in values
