.
Answer:
55/77
Step-by-step explanation:
The sum of the numbers in the given fraction is 5+7=12. The sum 132 is 11 times that value. Multiplying 5/7 by (11/11) will give the fraction you want:
(5/7)×(11/11) = 55/77 = 5/7
Area of a rectangle
is LxW. We let x = width and x+20 = length. Using the formula we will evaluate;
A = LxW
4800 =
(x+20)(x)
x² + 20x –
4800 = 0
We will get
the factors of it to determine x values, in this case, we are only looking at
the positive x value since are dealing with the area.
x² + 20x +
4800 = 0
(x+80)(x-60)
= 0
(x + 80) = 0 | (x-60) = 0
x = - 80 | x = 60
x = 60, this is the width
x +20 = 80, this is the length
