Answer:

2 1/2cm  is the answer for w

Step-by-step explanation:

the reason for this is because the total area for the triangle is 17 cm

and from whats shown on the rectangle it has only 12 so far so that means the w equals 2 1/2 because 12 + 2 1/2 + 2 1/2 = 17 so therefor the answer is 2 1/2cm

hope this helps :)
