Answer:
56sq. cm
Step-by-step explanation:
Area of a trapezoid = 1/2(a+b)h
a and b are the parallel sides
h is the height of the trapezoid
Find the f=diagram attached. from the diagram
a = 9cm
b = 5 + 9 + 5 = 19cm
h = 4cm
Substitute
Area of the trapezoid = 1/2 * (9+19)*4
Area of the trapezoid = 1/2 * 28 * 4
Area of the trapezoid = 28 * 2
Area of the trapezoid = 56sq. cm

Answer: 3
Step-by-step explanation: 3x4=12 or 12/4=3
Answer:
-7
Step-by-step explanation:
let the first term be a
thus, a=56
common difference d= U2-U1 = 49-56= -7
X=12
