Write the information given in the picture in the form of an equation. Also, find ‘y’ in the following figure.

(a) 5 cm
(b) 2 cm
(c) 6 cm
(d) None of these

Hint: In this given problem, we have to write down the information into an equation form. So, we first try to analyze the given information and write down what is given to us. Then once we have made up the equation, we can just simplify and solve the equation to find the value of y. Thus, we get our needed solution.

Complete step by step solution:
According to the question, we are to write the information given in the picture in the form of an equation. Also, we are to find the value of y from the given figure.
To start with, we can see from the image, the total length of the pen is 13 cm.
Watching from the left, the first part of the pen provides us with the length of y cm.
And, we have the second part of the pen with the length of 8 cm.
Thus, we now get the total length as, y + 8 cm.
And we also have the total length as, 13 cm.
Then, we can write the information given in the image as, y + 8 =13.
Subtracting 8 from both sides, we get, y = 13 – 8 = 5 cm.

So, the correct answer is “Option A”.

Note: In this problem, we have used a picture to get the information out of it. This problem is a typical easy problem, which can be solved very easily. Mensuration is also an example of getting solutions from pictures and finding the solution.
