what is asked:find its perimeter

what are the given fact:13.8 cm long and 9.7 cm wide

what is the hidden what is the opperation to be used:A rectangle

how to solve the problem;47 cm

Step-by-step explanation:

Perimeter of the Rectangle

The perimeter of the rectangle refers to the total length of all the sides of the rectangle. Rectangle is a four-sided polygon where opposite sides are always the same in size. Therefore, to find the perimeter of the rectangle, you have to find the sum of twice its length and twice its width.

P = 2L + 2W

Let us now find the perimeter of the rectangle above.

Given:

length - 13.8 cm

width - 9.7 cm

Equation:

P = 2(13.8 cm) + 2(9.7 cm)

Solution:

P = 2(13.8 cm) + 2(9.7 cm)

= 27.6 cm + 19.4 cm

= 47 cm

Final Answer:

47 cm
