Answer:
If Length is decreased by 10% then it would become a square.
Step-by-step explanation:
Given:
Area of Rectangular field = 1440 sq. m
Perimeter = 152 m.
We need to find which one needs to be decreased by what percentage to make it a square.
Solution:
Let length be denoted by 'l'.
Also Let width be denoted by 'w'.
Now we know that Area of rectangular field is given by Length times width.
framing in equation form we get;
Also we know that Perimeter of rectangular field is given by 2 times sum of Length and width.
framing in equation form we get;
Now Substituting equation 2 in equation 1 we get;
Now we will find the root by factorizing the same we get;
Now solving for each to find the value of 'w' we get;
So We can say that;
Width = 36 m and Length = 40 m
Now we need to find out of length or breadth which one is to be decreased by what percentage to make it a square.
We know that square has all sides same.
So from the data we found we can say that if length is decreased by 4 then length and breadth(width) both will be equal.
So to find percentage decreased we will divide length to be decreased by total length and then multiply by 100.
framing in equation form we get;
percentage decreased =
Hence If Length is decreased by 10% then it would become a square.

Explanation:
sum -- the result of addition: 5x+1
term -- a constant, variable, or product of a constant and one or more variables. In the more general sense, a term is any part of the expression that can be considered by itself. An example is 5x
product -- the result of multiplication: 9(5x+1), where 9 is multiplied by the sum (5x+1)
factor -- part of a product: x
quotient -- the result of division: 9(5x+1)÷3
coefficient -- a constant, or the constant that multiplies the variables in a term: 5

<em>Additional comment</em>
The way this is written, there will be the tendency to think of 3y as a term in the same sense that 5x is a term. That would be incorrect. The Order of Operations has you interpret this expression as ...
