Question

the cross section of a Canal is a trapezium shape is the canal is 10 metre wide at the top 6 metre wide at the bottom and area of cross section is 72 square metre find the depth of the kennel​

Answer 1

Answer:

Trapezium

Area =h/2(a+b)

h = depth, a,b,parallel sides

A = 72m2, a = 10m, b = 6, h=?

.72 = h/2(10+6)

72x2 = hx16

h = 72x2/16=9m

depth h=9m
