Question

if the diagonal of a square field is 16 cm, what is the area?​

Answer 1

Answer:

128

Step-by-step explanation:

Diagonal of a square field (d)=16m

Area of square field (A) =?

Now from right triangle having diagonal as hypotenuse and sides of square forming base and altitude of triangle

d^² = a^² +a^²

Where a is side of square field

16^² =2a^²

16×16/2 = a^²

a^² =128
