Answer:
c
Step-by-step explanation:
because are of trapizium =( a+b/2) × h
First, find the length
L^2+W^2=D^2 )L for length, W for width, D for diagonal)
L^2=25^2-15^2=625-225=400
L=20
A=1/2 of L*W= (1/2)*20*15=150 square inches
B) No, set of side lengths does not satisfy Triangle Inequality Theorem
