Answer:
5
Step-by-step explanation:
Assuming we want to evaluate |z|, given that, z=4+3i.
Then, by definition of modulus,



Therefore the modulus be of the given complex number is 5 units
Answer:
the answer for this question is 15/14
to find area the formula is area = l×b
here length is 1 1/4 and breadth is 3/4 so l×b = 1 1/4=5/4 so 5/4×3/4=15/14
