(a) 17.5 cm
(b) 10 cm
D
(c)) 15 cm
(d) 22.5 cm

Answer 1

Answer:

$c)15 \: cm$

since ABCD and BDMN are two squares

AC and BD are diagonals for square ABCD, also BD is the side of square BDMN. since diagonals of a square are equal and all sides of square are equal.

AC=BD since diagonals of same squares

BD=MN since sides of same squares

therefore AC=MN=15cm.
