Answer:
A =315 cm^2
Step-by-step explanation:
The area of a trapezoid is found by 
A = 1/2 (b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 13+29) *15
A  = 1/2 (42)* 15
A =315 cm^2

Answer:

Step-by-step explanation:
velocity of river with respect to ground = 4 mi/h south

Velocity of swimmer with respect to river = 2 mi/h east

According to the formula of relative velocity 


Where, V(S,G) be the velocity of swimmer with respect to ground, it is true velocity of swimmer.
