Answer:
28 cm^2
Step-by-step explanation:
a= ( b1+ b2 / 2 ) h
a= ( 5+9 /2)*4
5+ 9 = 14
14/2=7
7*4 =28
To find a perpendicular line, the slope is opposite reciprocal. The slope would be -4x.
Put in point slope form:
y - 7 = -4(x - 2)
y - 7 = -4x + 8
y = -4x + 15
(line perpendicular to given equation and goes through the point)
Hope this helps!! :)
