A ladder touches a bench and leans on a 4m wall. If the bench is 50cm high and is 1 m away from base of the ladder, the distance from wall to base of the ladder

Question

I have a math test in 2 days. It’s urgent.

Answer 1

Draw and label a diagram. "d" is the distance from base to bench.

Using similar triangles

 

0.5 : 4 :: 1 : d + 1        proportion

(4)(1) = (0.5)(d + 1)    product means/extremes

 

Can you solve for d and answer?
