Would the distance be different than what they measured?

Question

Carmina and ANtone measure that the distance between the spots where they are standing is 10 feet, 7 inches. When measuring, Antone held his end of the tape measure up 4 inches higher than Carmina's end. If Carmina and Antone had measured the distance between them along the floor, would the distance be appreciably different than what they measured?

Answer 1

Draw and label a diagram.

The length of the tape (127 in) is the hypotenuse.

The end of the tape held up 7 in is the short leg

d represents the long leg, the real distance.

 

127² = 7² + d²

 

Now you calculate the value of d.
