Answer:
8.9' ft is the length of diagonal
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
