Question

The perimeter and area of a square with the side 275mm. Give the perimeter in cm and mm and the area in mm²and cm²

Answer 1

Answer:

If a square whose side is 275mm​ the area of the square is 75625 mm² and the perimeter is 1100mm

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
• use the unit conversion 1mm=0.1cm

From the question, it is given that

the side of the square is $l=275mm$

therefore the area of the square using equation 1 is

$A=275*275=75625mm^{2}$

also in the centimeter area is $A=756.25cm$

using equation 2 we get

the perimeter of the square is $P=4*275=1100mm$

and in the centimeter $p=110cm$
