Question

b. What is the length of the side of a square with a perimeter of 48 mm?​

Answer 1

Answer:

$\huge \mathcal{ \fcolorbox{aqua}{azure}{ \red{ Answer}}}$

Since the field is square, each of the 4 sides are equal. Side + Side + Side + Side = perimeter or

side x 4 = 48

side = 48/4

side = 12

The area of a rectangle is

width x length = area

Since the width and length of a square are the same, the area of this field is:

side x side = area

12 x 12 = 144 square meters

Answer 2

Answer:

The length of each side is 12 cm.

Step-by-step explanation:

The perimeter of a square is calculated by the formula:

P=4a,where P=perimeter, and a=length of any side, all sides being equal in a square.

From the given data we write:

48=4a

Divide both sides by 4.

12=a

The length of each side is 12 cm.
