Question

find the length of diagonal of a square with side 8cm ​

Answer 1

8√2

Step-by-step explanation:

length of the square = 8cm

d=√8²+8²

√64+64

√2×64

8√2 cm

hence length of the diagnal = 8√2cm

Answer 2

Answer:

11.34 (approx)

Step-by-step explanation:

By Pythagoras theorem p^2 + b^2 = h^2

here p= 8 and b= 8

Therefore, 8^2 + 8^2 = h^2

64+64= h^2

128 = h^2

root 128 = h

11.34 (approx) = Diagonal
