18cm is the area and perimeter. the width is 3cm.
For a square, all 4 sides are the same length, so perimeter is 4 times length of a side. So, 4 x 3cm = 12 cm

what is the perimeter and area of a rectangle 3cm long and 3cm wide
16cm.
18cm is the area and perimeter. the width is 3cm.
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
For a square, all 4 sides are the same length, so perimeter is 4 times length of a side. So, 4 x 3cm = 12 cm
Since a square has four equal sides, the length of one side is (24/4)cm=6cm and the area is length X width or 6cmX6cm=36cm2. One fourth of A's area is then 36cm2/4=9cm2. Square B then has a length and width of 3cm and its perimeter is 2(L + W)=2(3cm+3cm)=12cm. STUPID
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*diameter

length + width = 20/2 = 10 length = 7cm, width = 3cm
what is the perimeter and area of a rectangle 3cm long and 3cm wide
16 cm 5cm+5cm+3cm+3cm=16cm
16cm.
I assume you are referring to a rectangle. Just add the lengths of all four sides.
The edge length would be 3 cm.
