Question

if the side of a square =x and area =x² and perimeter 20 find area

Answer 1

side of square = X ......( given)

perimeter of square = 20........( given)

area of square = x² .........( given)

using the formula of perimeter of square ---

perimeter of square = 4 ×side.

20 = 4 × x

x = 20/4

x = 5

hence the side of square = 5.

now, if we have side then we can find area by equation = side²

=> 5²

=> 25

hence the area of square => 25

Answer 2

$\mathfrak{ dear\:user}$

given -$SIDE=x$

$AREA=x^{2}$

$PERIMETER=20m$

to find -$SIDE,AREA$

PERIMETER=4S

$PERIMETER=4S\\4S=20\\S=20/4\\S=5$

AREA=S²

$AREA=S^{2} \\AREA=5^{2} \\AREA=25$
