Answer 1

Answer:

hey your answer is as follows

so pls mark it as brainliest

Step-by-step explanation:

now as we know that diagonal of square=root2 times that of its side

thus here given diagonal=8 cm

hence each side=8/root2 cm

so now area of square=side square

=(8/root2)square

=64/2

=32 cm.square

hence area of square whose diagonal is 8 cm is 32 cm.square

Answer 2

Answer is 32cm²

Explanation:

Diagonal of a square = s√2

Given:

Diagonal = 8cm

s√2=8

s=4√2cm

Area of square= s×s

4√2cm × 4√2cm

= 32cm²
