Question

ABCD is a square. If the perimeter of the square is 68 cm and one ofvrhe siagonal is 16 cm find other​

Answer 1

retype your question ...

if you are asking to find the other diagonal there is no doubt that the diagonal will be of 16cm because the diagonals of the square are always equal

Answer 2

Answer

30 cm

Step-by-step explanation:

Given ABCD is a square

perimeter of square = 68 cm

so side of square = 68 /4= 17cm.

now if one diagonal(suppose BD) is 16 cm

then AO=BO=8 cm

now according to Pythagoras triplet

(17)^2 = (8)^2 + (other diagonal )^2

289= 64 + (other diagonal )^2

(other diagonal )^2 = 289 - 64 = 225

other diagonsl = square root 225

other diagonal (AO) =15

so full diagonal AC = 15 +15=30cm.
