Question

2. Find the length of a square whose perimeter is 320 m.

Answer 1

Answer:

length of side=x

perimeter = 4a

but, perimeter = 320m(given)

perimeter = 4a = 320m

a = 320/4

a = 80m

hope it will help..☺️☺️

Answer 2

$\large \rm \gray{Explanation:} \\\rm \blue{Given : Perimeter \: of \: the \: square \: park = 320m }\\\rm \blue{We \: know \: that, }\\ \rm \blue{Perimeter \: of \: a \: square = 4 × side }\\ \rm \blue{⇒ 4 × side = 320 }\\ \rm \blue{⇒ side = \frac{320}{4}} \\\rm \blue{⇒ side = 80m} \\\rm \blue{Area \: of \: a \: square = side²} \\\rm\blue{Hence, Area \: of \: the \: square \: park = 80² = 80 × 80 = 6400m² }$
