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.

Find mystery number
In-s [12.5K]

The number is less than 190,000 and greater than 180,000

5,000 more than the number has 187 thousands

2000 less than the number has 4 hundreds


180, 000 <n> 190, 000

180,000 + 2000 = n = 5000-187, 000

182,000 = n = 182, 000  

Or,  

 180, 000 <n> 190,000                    

 n + 5000= 187, 000                           n – 2000 = 180, 000

 n= 187, 000- 5000                             n = 180, 000 + 2000

 n= 182, 000                                       n= 182, 000

the points are (-6, -3) and (-2, -8)

the formula for slope is y2-y1/x2-x1

y2 is -8

y1 is -3

x2 is -2

x1 is -6

(-8+3)/(-2+6)

(-5)/(4)

-5/4 or -1.25

Tickets for a concert cost $2 each for children and $5 each for adults.A group of 30 people consisting of children and adults pa
noname [10]
Let,
the no. of adults be "x"
then, the no. of childern = total people - total adults 
                                   = (30 - x)
Now,
According to the quesiton,
2 (30 - x) + 5x = 87
60 - 2x + 5x = 87
60 + 3x = 87
3x = 87 - 60
3x = 27
x = 27 / 3
x = 9

So, there were 9 adults in the group
