Answer:

area of a square if sum of its diagnals is 100 cm

Answer 2

$\huge \underbrace \mathtt \blue {Solution}$

Diagonals of a square are equal

So, length of a diagonal = 50 cm

Diagonal = side √2

So, side of the square = 50/ √2 or 25 √2

Area of the square = side × side

= 25 ✓2 × 25√2

= 1250 cm²
