Answer:

20 m

Step-by-step explanation:

Use pythagoras theorem

hypotenuse = ladder = 29 m

height = wall = 21 m

base ?

hyp² = base² + ht²

base² = hyp² - ht²

base² = (29 m)² - (21 m)²

base² = 841 m² - 441 m²

base² = 400 m²

base = 400 m²½...(sqaure root)

base = 20 m

Distance between ladder and wall is 20 .
