[amp_mcq option1=”R + T” option2=”T – R” option3=”$$\\sqrt {{{\\text{R}}^2} + {{\\text{T}}^2}} $$” option4=”R – T” correct=”option2″]<\/p>\n

The correct answer is $\\sqrt {{{\\text{R}}^2} + {{\\text{T}}^2}}$.<\/p>\n

The width of a beam is the distance between its two supports. In the case of a stair, the two supports are the wall on one side and the stringer beam on the other side. The rise and tread of a stair are the vertical and horizontal distances between each step, respectively.<\/p>\n

The width of a stair step is therefore equal to the square root of the sum of the squares of the rise and tread. This is because the width of a stair step is the hypotenuse of a right triangle, where the rise and tread are the legs of the triangle.<\/p>\n

For example, if the rise of a stair step is 6 inches and the tread is 8 inches, then the width of the stair step is $\\sqrt {{{\\text{6}}^2} + {{\\text{8}}^2}} = \\sqrt {100} = 10$ inches.<\/p>\n

The other options are incorrect because they do not take into account the rise and tread of the stair.<\/p>\n","protected":false},"excerpt":{"rendered":"
