Answer:
Step-by-step explanation:
see the figure below
As O is mid point of rectangle
distance between O to AB and DC is same
also distance between O to AD and BC is same
OP and OQ are perpendiculars so it is straight
and OP divides AB into equal segments as distance between O to AD and BC is same
same goes with OQ
First you simplify both sides of the equation, then isolate the variable and that’ll give you c=3b/4
