Question

ABCD is a rectangle. if AC = 3y/5 anf BD= 3(y-4), find the length of each diagonal

a.) 4; LN = MP = 4
b.) 3; LN = MP = 7
c.) 1; LN = MP = 67
d.) 5/3; LN = MP = 29/3

Answer 1

Remember please that Diagonals of a Rectangle are equal to each other: 3y/5 = 3(y-4)
So
3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options
