Question

how to find perimeter and area of a square whose side is 17 mm​

Answer 1

Answer:

perimeter=4×sides

=4s

=4×17

= 68 mm

Area = side×side

=s²

=17²

=289 mm

Answer 2

Answer:

If a square whose side is 17 mm​ the area of the square is $289mm^{2}$ and the perimeter is $68mm$

Step-by-step explanation:

• A square is a polygon with four equal sides

• The area of a square with its side represented by (l) is given by the formula

       $A=l^{2}$ equation 1

• The perimeter is the total linear distance along the boundary, for a square, it is equal to  $P=4l$ equation 2

From the question, it is given that

the side of the square is $l=17mm$

therefore the area of the square using equation 1 is

$A=17*17=289mm^{2}$

using equation 2 we get

the perimeter of the square is $P=4*17=68mm$
