The length of one wall in the room plan is 13 in. If the room was square, all the sides would need to be 13 in.
Since the walls are at right angles, we can use the Pythagorean Theorem to solve this. <em>(a^2 + b^2 = c^2)</em>
(I drew a diagram. It looks like this: A square is cut across diagonally by a line labeled <em>"hypotenuse, 15.26 in."</em> The right triangle created by the line is lightly highlighted. The sides of the triangle adjacent to the right angle are labeled <em>"leg a, 13 in." and "leg b, ?"</em> for unknown value. Picture is attached!)
To find the value of the unknown leg, we can subtract the value of leg a from the hypotenuse to find the value of leg b.
c^2 - a^2 = b^2
Insert values into equation and solve.
15.26^2 - 13^2 = b^2
232.87 - 169 = b^2
Square root of 63.87 = b
The value of the unknown leg would be 8 inches. Since all sides of the room would have to be 13 inches for the room to be square, the room is a rectangle.
The graphs are attached. Each graph is transformed by a horizontal translation or vertical translation or a reflection.
