=400/2
=200cm²
Hope this answer helps you!!!

Answer 2

Answer:

$Area \: of \: the \: given\\ \: square (A) = 200 \: cm ^{2}$

Step-by-step explanation:

Given length of the diagonal of a square (d)=20cm

/* We know that,

$\boxed {Area \: of \: a \: square (A) = \frac{d^{2}}{2}}$ *\

$\implies Area (A) = \frac{(20 \:cm)^{2}}{2}\\=\frac{20cm \times 20cm }{2}\\</p><p>= 200 \: cm^{2}$

Therefore,

$Area \: of \: the \: \\given \: square (A) = 200 \: cm ^{2}$
