Find the diagonal $d$ of a square if area $A = 36 cm$ .

Answer

$62$

Explanation

STEP 1: find side $a$

To find side $a$ use formula:

After substituting $A = 36 cm$ we have:

A = a^{2}

a^{2} = 36 cm

a = 36 cm

a = 6

STEP 2: find diagonal $d$

To find diagonal $d$ use formula:

d = 2 \cdot a

After substituting $a = 6 cm^{0}$ we have:

d = 2 \cdot 6

d = 62
