#

Ok so area of a triangle is 0.5 X base X height

#

The base is the distance from O to B (since B is where it crosses the X axis)

#

Which is 41/4

#

The height is the distance from the X axis to A

#

So 11

#

It should be (11x41/4x0.5)

#

It should be 56.375 unless I have messed something up

#

OMG THE HEIGHT IS JUST 11 THATS WHY I MESSED UP 😭 I FOUND THE MIDPOINT OF OB AND THEN FOUJD THE DISTANCE BETWEEN A AND THAT MIDPOINT BUT IT WAS WRONG
