Step-by-step explanation:
The given expression is [
]
We can rewrite the fractions as,
= 

Now we will substitute the fractions in the expression,
![[-(5+\frac{1}{4})]-[-(7+\frac{1}{2})]](https://tex.z-dn.net/?f=%5B-%285%2B%5Cfrac%7B1%7D%7B4%7D%29%5D-%5B-%287%2B%5Cfrac%7B1%7D%7B2%7D%29%5D)
= 
= (-5 + 7) + 
= 2 + 
= 2 + 
= 
Therefore, Option (2). will be the answer.

The Area of rectangle = 80 unit².
<h3>What is Area of rectangle?</h3>
The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.) The area of a rectangle is the number of unit squares that can fit into a rectangle. Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc. You can use the formula of the area of a rectangle to find the space occupied by these objects. For example, let us consider a rectangle of length 4 inches and width 3 inches.
from figure (a)
DE= 40/8 = 5
BC= 100/5 = 20
Now,
AC= AB + BC= 8+ 20 = 28
CE= CD + DE = 10+5= 15
So, area of rectangle
= AC* CE
= 28* 15
= 420
Now, from figure (b)
CD= 24/12= 2
DE= 12/4 = 3
AC= AB+ BC= 14+ 4= 16
CE= CD + DE= 2+3 = 5
So, Area of rectangle= 16*5 = 80 unit²
