Question

If the diagnal of a square is 90m,then find its area?

Answer 1

Answer:

Step-by-step explanation:

Diagonal of a square =√3a

Therefore, 90=√3a

a=90/√3

a=30√3

Area=a²

=(30√3)²

=900*3

=2700m²

Answer 2

Answer:

Area of the square (A)=4050m²

Explanation:

Diagonal of a square (d)=90m

Area of the square (A)=d²/2

= (90m)²/2

= 90m × 45 m

= 4050 m²

Therefore,

Area of the square (A)=4050m²
