Sheldon makes a scale model of his bedroom. The dimensions of the floor of the model are 15cm long and 12.5cm wide. He uses a scale of 1: 40. a. What is the actual length of his room?

b. What is the actual width of his room?

c. What is the actual area of his bedroom floor in m²?

rounding to the nearest thousandth would be 452,000

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
