Question

The floor of a rectangular living room is 21 feet by 28 feet. What is the distance between
opposite corners of the living room?

Answer 1

Answer:

35 feet.

Step-by-step explanation:

To find this, we will need to use the Pythagorean theorem to solve for the diagonal length. Call this diagonal length 'd'.

d² = 21² + 28²

d² = 1225

d² = 35.

Thus, the diagonal length is 35 feet.
