Answer:
area of trapizoid=49 unit^2
Step-by-step explanation:
area of trapizoid=0.5(x+y)h
where, x=parallel side=3units
y=parallel side =11 units
h=distance between two parallel sides
area of trapizoid=0.5(x+y)h..............(1)
put x=3 units,y=11 units and h=7 in equ (1)
area of trapizoid=0.5(3+11)7
area of trapizoid=
area of trapizoid=49 unit^2 answer
