Question

what is the altitude corresponding to the side of length 8.5 CM in a parallelogram whose area is 34 CM square

Answer 1

Given, 
Area of paralellogram = 34 cm^2 
Base = 8.5

Altitude = Area/ Base 
= 34/8.5
= 4 cm

Hope This helps :)

Answer 2

Area of parallelogram = base * height
34 cm =8.5* height
34 =85/10 * h
34*10/85 = height
Height = 4
