Question

Riyo has a 20 foot long string of lights she wants to hang diagonally across her bedroom ceiling. If her bedroom is 14 feet wide and 15 feet long, is the string of lights long enough to hang diagonally across the ceiling?

Answer 1

Answer:

0.5 shorter than required

Step-by-step explanation: size of room is 14 feet wide and 15 feet long

the length of diagonal will be square = $(diagonal){2} = (14){2} +(15){2}$

= 196+225= 421

diagonal length = square root of 421= 20.5

so Riyo will find string of lights shorter by 0.5 feet.
