In the given figure ABCD is square and OE = 7 cm.
Length of diagonal of the square is :
Answer & explanation
Correct answer: option 1
OE = 7 cm = radius of semicircle
Here, OE = OA = OD = 7 = radius and
AD = OA + OD = 7 + 7 = 14 cm = side of the square
Diagonal of square = \(\sqrt {2}\) side
= 14 \(\sqrt {2}\) cm
