Answer 1

hello mate!!

here is your answer

solution:

the perimeter of a square: 84 cm

we know,.

perimeter of a square= 4× side... ( formula)

therefore,

84= 4× side

84/4= side

21= side

therefore,

side of the square = 21 cm

now,

according to formula for area of a square,

area= side× side

area= 21× 21

area= 441 sq cm

hope this helps!☺✌❤
