Question

Maria looked at the architectural plan of a room with four walls in which the walls meet each other at right angles. The length of one wall in the plan is 13 inches. The length of the diagonal of the floor of the room in the plan is approximately 15.26 inches.

Answer 1

This question is essentially the same as the other. If you actually understood the concept, you would be able to do this. Can you try to attempt this question?

Answer 2

i did

Answer 3

lemme draw it

Answer 4

\[15.26^{2} = 13^{2} +b^{2} ~~~~~232.87 = 169 + b ^{2}~~~~~232.87=169 + 63.87~~~~~15.26=13^{2}+7.99^{2}\]

Answer 5

*13^2+7.99^2

Answer 6

Answer 7

i dont think it is a square because a square has all equal sides. this means that the missing length should be 13, not 7.99

Answer 8
