Question

the area of a square is 16200 m square find the length of the diagonal

Answer 1

Hey...

Here is your answer...

Area of square = 16200 m²

By the formula, Area of square = 1/2d²
=> 16200 = 1/2d²
=>. 32400 = d²
=>. d = ± 180 m
=> d = 180 m ( Neglecting -180m)

Hence, the length of diagonal of a square is 80m.

Hope this would help you.

Answer 2

area of a square = 16200 m²
Side × side = 16200
side² = 16200
side = √16200
side = √8100×2
side = 90√2 m

Side of the square,a = 90√2
Diagonal of the square = √2 × a
= 90√2(√2)
= 90(2)
= 180 m
