The area of a rectangle is the multiplication of its width times its length, that is:
area = width*length
We have to write as an equation the information about the relationship between the width and the length, they say the width is 1/4 of the lenght, this is:
width = lenght/4
now we substitute the data we have:
area = width*length
144 = (length/4)*length
length^2 = 4*144 = 576
the length is raised to the second power because we had to multiply length*length, so to solve the last equation we had to take the square root to both sides:
length = √576
<span>length = 24
</span>so the length of the banner is 24 feet, and we know that:
<span>width = lenght/4
</span><span>width = 24/4
</span>width = 6
so the width is 6 feet
A) 9 plus 4
B) 13
C) x plus 5
D) 5
E) 4
Hope this is right sorry if it’s wrong
A real world example could be:
Consider x is time in minutes
<span>Consider y is the amount of fish food required in grams</span>
25% 0ut of 27 should be 6.75, as let's say 27 =100%
So to get 25% we have to divide 100 by 25, to which the answer =4.
Same we have to do to 27- divide it by 4 to get the answer.
I hope it's right.
