So a rectangle has 4 sides. The two long sides and the two shorter sides in an rectangle are the same length.
Knowing this we know that one of the sides is 6cm long, that means the side opposite it must also be that same length.
The perimiter is the same as the distance it takes to walk all around the shape, we already know that the perimiter is 16cm.
And we already know that two of those lines that you'd have to walk are 6cm so we know that to walk two sides of the rectangle that's 12cm.
That means that the other two sides must take 4cm to walk to make the perimiter add up to 16cm.
Now remember that we said that a rectangle has 2 long sides and 2 short sides that are equal in length? well we know the two long sides are equal now at 6 cm each, and we know that the 2 short sides add up to 4cm...and they have to be the same size, so each short side msut be 2cm long each.
Now that we know all the sides length, we multiply length x bredth to get aera
that's 6cm x 2cm = 12cm2

156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
you need length and width length multiply width = area length + length + width + width = perimeter
Area is length times width, perimeter is twice the sum of length and breadth.
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)

if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm
Perimeter is the length of a closed line around an area. A rectangle is an area. If each long side of the rectangle is 12 cm and each end of the rectangle is 9 cm, the total length is 14+14+9+9 or 46 cm.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
If the rectangle is a square, the perimeter is 48 cm. If not, there are a lot of possibilities.

24000 sq.cm.
you need length and width length multiply width = area length + length + width + width = perimeter
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
Area is length times width, perimeter is twice the sum of length and breadth.
