Question

the area of a square is 16200msq .Find the length of its diagonal

Answer 1

a^2 =16200
$a = \sqrt{16200}$
a=127.7 Now using pythagoras find its diagonal

Answer 2

Area of square=S²
16200m²=S²
√16200=S
127.29=S

All Side of square is equal.
So using Pythagoras theorem can find diagonal

x²=127.29²+127.29²
x²=16202.74+16202.74
x²=32405.48
x=√32405.48
x=180.02m
