Question

The following expressions represent the total area of the rectangle is?

  1. 5(2 + 3)    
  2. 3(2 + 5)    
  3. 2(3 + 5)    
  4. 2(3) + 3(5)    

Hint:

Distributive property is the law in which we can solve problems which are in the form a(b+c). To solve this type of problem we just have to multiply a with b and then c which can be written as ab+ ac and then finally add them. It is one of the common formula which is used to solve problems. Here, we have to solve the problem using distributive property.

The correct answer is: 2(3 + 5)


    In the it is given that,
    The length of the rectangle = (3+5) unit
    The breadth of the rectangle = 2 unit
    Here, we have to find the area of the given rectangle.
    As the area of the rectangle will be length × breadth.
    So, the expression will be 2(3+5) unit.
    Therefore, the correct option is c, i.e., 2(3+5).

    In distributive property, when a factor is to be multiplied with the sum of two numbers, we do not directly add the two numbers and then multiply the sum with the factor. Rather, we multiply both the numbers with the factor differently and then add the multiplication value.
