Answer:
The width is 8 units
Step-by-step explanation:
This is a variation problem we are to work with.
Length is inversely proportional to width, let length be l and width be w
modeling the statement mathematically, we have lw = k where k is the proportionality constant
Now let’s get k from l = 12 and w = 6
k = 12 * 6 = 72
Now for the second rectangle also;
lw = k given l = 9
9w = 72
w = 72/9
w = 8
Answer:
87.8 square meters
Step-by-step explanation:
First of all, find the area of the three recthangles.They are all 9m long and 3m wide. 9*3 is 27, and since there are three of them, 27*3 is 81.
To find the area of the two triangles, you could do 3*2.6. Normally, you would halve the values because they are triangles but since there's two of them it cancels out.
3*2.6 is 7.8, and adding that to the area of the rectangles gets the equation 81+7.8 which comes out to 87.8 square meters.
We have
we have x is less than or equal 50/7
