Question

ABCD is a rectangle. Its diagonals meet at O. Find the value of x if BO=3x+4 and
OC= x+8 .Also find the length of its diagonals.(Lengths are in cm).

Answer 1

Answer:

as the diagonals are bisect each other

3x+4=x+8

=> 3x-x=8-4=4

=> 2x=4

=> x=4/2=2

so, BO= 3x+4=3.2+4=6+4=10

length of the diagonal=10×2 cm=20 cml
