Question

What is the sum of the lengths of the two blocks in the given figure?

• A. 68 in
• B. 88 in
• C. 48 in
• D. 77 in

Answer 1

The correct option is B 88 in

Given, the length of the blue block = 47 in
Also, the length of the yellow block = 41 in

So, the sum of the lengths of the two blocks = (47 + 41) in

Let’s add 47 and 41.

Step 1: Let’s reduce the addend 41 to 40 and then add 40 to 47.
41 - 1 = 40
47 + 40 = 87

Step 2: Let’s add 1 to 87 to get the final answer.
87 + 1 = 88

So, (47 + 41) in = 88 in
So, the sum of the lengths of the two blocks is 88 in.
