The perimeter of a square = 4(side) substitute 40 m for the perimeter,40 m = 4(side) divide by 4 to both sides,10 m = sideThe area of a square = side^2 substitute 10 m for the side,Area = (10 m)^2Area = 100 m^2
Perimeter of rectangle: 2*(7+6) = 26 m
Perimeter= 2(l+b) =2*39 =78m = Area =l*b = =24*15 =360m
Area = length x width; 10 m x 6 m = 60 m2 (also written as 60 square metres)
A shape is a nebulous term. It may mean a triangle, a square, or a pentagon in 2D, or a block or pyramid in 3D etc. The perimeter and area cannot be found without defining the shape first. How many dimensions? How many sides? For example, if the shape is a square, which has 4 edges, its perimeter = 4 * 4 [m] = 16 [m] and its area = 4 [m] * 4 [m] = 16 [m^2].
