Question

please tell the answer for this one question no. 12

Answer 1

Area=L*W but for square L=W
therefore, L^2=16200
Using Pythagoras theorem,
L^2+W^2
L^2+L^2=16200+16200
             = 32400
Diagonal= 180

Answer 2

Area of square = 16200 m^2

Side ^2 = 16200

$a = \sqrt{16200} \\ a = 10 \sqrt{162} \\ a = 10 \sqrt{81 \times 2} \\ a = 10 \times 9 \sqrt{2} \\ a = 90 \sqrt{2}$
Side of square = 90 root2

Diagonal = side *root 2

Diagonal = 90 * root2 * root 2

= 90 * 2

= 180 m
