If given the total perimeter only it is impossible to do. However, if the lengths of each part of the perimeter are given (or can be worked out from the lengths given) then split the shape's area up into areas of shapes whose area you do know how to calculate, calculate each area and add them up. For example if you have a hexagonal L shape with lengths 1cm, 3cm, 3cm, 1cm, 4cm, 4cm, (all angles 90o) it can be split into two rectangular areas, one of 1cm x 3cm (from the top of the back of the L to the top of the piece across the bottom) and the other of 4cm x 1cm (all the way across the bottom of the L).
Area: Find some of the lengths, then cut the L in half and work it out from there. Perimeter: Add all the lengths together.
Pyramid (regular) Lateral area : pl/2, where l = slant height : p = base perimeter Total area : pl/2+B where B = Base area.
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
Area = 144 sq inches => Length of side, L = 12 inches => Perimeter = 4*L = 48 inches.
There are many shapes for calculating perimeter such as:Rectangle: 2(L+W) where L=length and W=weightSquare: 4s where s=# givenTriangle and most shapes: add up all the sidesCircle: 2∏r

perimeter of rectangle=2(l+b) l=length of the rectangle b=breadth of the rectangle
Add all sides of the area together to get the perimeter.Is the area is a Rectangle, then you can use the following formula:P = 2 L + 2 W(which means Perimeter equals two times the length plus two times the width)
Area: Find some of the lengths, then cut the L in half and work it out from there. Perimeter: Add all the lengths together.
as perimeter =8 so 4l=8 , so l=2. now area= [l][l]=(2)(2)=4
Perimeter l+l+w+w= 70ft Area LxW =300 sqft
Pyramid (regular) Lateral area : pl/2, where l = slant height : p = base perimeter Total area : pl/2+B where B = Base area.
A square that measures 4 per side. Perimeter = L + L + L + L = 4L = 4*4 = 16 Area = L * L = 4*4 = 16 Although technically they won't be equal since perimeter has units of length, while area has units of squared length.

Represent the length of the rectangle by L and the width by W. The perimeter = 2L + 2W = 2(L + W). The area = L x W.
