A rectangular state flag has the dimensions 7' x 5 1/2' feet. How long is it's diagonal?

8.9' ft is the length of diagonal

Step-by-step explanation:

The length of a rectangular state is 7' feet

the breadth of rectangular feet is 51/2' feet

to get the length of diagonal, we use the pythagoras theorem since the diagonal has converted the rectangular state to right angle triangle

hypotenuse² = opposite² + adjacent²

hypotenuse² = 7²+5¹/₂² = 49 + (11/2) ² = 49 + 121/4 = (196+121) / 4 = 317/4 =

hypotenuse = √ (317/4) = √317/√4 = 17.8044938148/2 = 8.9022469≈8.9
