Answer: EF = 12 is the correct answer.
Step-by-step explanation: EF = GP - FP = 16 - 4 = 12Given that GH=10, GP=16, and FP=4. We have to find the value of EF. We can use this formula to find it:EF = GP - FP = 16 - 4 = 12So the value of EF is 12. In the given figure, ABCD is a rectangle and GP and GH are the diagonals. EF is the length of the rectangle.Therefore, EF = 12 is the correct answer.
