8th-grade math homework help

Answer 1

Answer:

option d 13.9 cm

Step-by-step explanation:

let the length be 11 inches and breadth be 8.5 inches

now using Pythagoras theorem we get

hypotenuse^2 = base^2 + length^2

hypotenuse^2 = 11^2 + 8.5^2

hypotenuse^2 - 121 + 72.25

$hypotenuse = \sqrt{193.25}\\hypotenuse = 13.9 cm$
