Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A = × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
The mode is the number that shows up the most
<span>103, 77, 90, 102, 103, 81, 78, 84, 84, 87, 99, 103, 118
reorder the numbers
77, 78, 81, 84, 84, 87, 90, 99, 102, 103, 103, 103, 118
103 shows up 3 times, one more than the next group (84)
103 is your answer

Answer:
slope of line parallel to given line=slope of given line
=9/2
slope of line perpendicular to given line=‐1/slope of given line
= -2/9
-6+9.8x=33 1/5
9.8x=39 1/5
x=4
