Question

Describe how you would draw a diagram for a problem about finding the total length for two strings, 15 inches long and 7 inches long.

Answer 1

you can draw 15 lines and 7 lines as inches and add them all together.
15+7=22

Answer 2

In the measurement the length is the distance of start to the last point of a object or line. To draw to finding the total length for two strings the two string should be draw such that the keep end point of the 15 inches long line to the first point of the 7 inches long line as shown in the attached figure

Given information-

The length of the first string is 15 inches.

The length of the second string is 7 inches.

How to add the length of two lines?

In the measurement the length is the distance of start to the last point of a object or line. If two lines are given with different length then keep the end point of first line to the start point of the second line and then measure for the total length.

In the given problem there is two different string. First one is 15 inches long and another one is 7 inches long.

To find out the total length of the two strings, the two string should be draw  such that the keep end point of the 15 inches long line to the first point of the 7 inches long line.

Lets draw and measure this string with following steps,

• Draw the 15 inches long line horizontally
• Draw one more line which is 7 inches long horizontally such that the 7 inches long line start from the end point of the 15 inches long line.
• Measure the total length of the line.

The total length of two string is equal to the sum of the two string as,

$15+7=22$

Hence to draw to finding the total length for two strings the two string should be draw such that the keep end point of the 15 inches long line to the first point of the 7 inches long line as shown in the attached figure.
