Answer:

52m

Explanation:

Parallelograms have two pairs of equal sides. The length of stairs and the length of the right side of rooftop to ground is the same.

The problem has cut up a right-angle triangle for you. In the right-angle triangle, the hypotenuse is actually the same length as the stairs.

Use the pythagorean theorem: a² + b² = c²

"c" is the hypotenuse (the longest side)

"a" and "b" are the other two sides

Substitute a = 22 and b = 47. Isolate c.

a² + b² = c²

22² + 47² = c²

2693 = c² Square root both sides of the equation

c = 51.89..... Exact answer in decimals

c ≈ 52 Rounded to the nearest metre (whole number)

Therefore the stairs are 52 metres long.
