Question

Find the area of a square whose perimeter is 40 cm​

Answer 1

Step-by-step explanation:

Electrons are the subatomic particles that orbit the nucleus of an atom. They are generally negative in charge and are much smaller than the nucleus of the atom

Answer 2

Formula of perimeter = 4 × s

$4 \times s = 40$

$s = \frac{40}{4}$

So side = 10cm

Area of squre = s × s

$10 \times 10 = 100$

So area of square is 100cmsq
