+128631 Perimeter of rectangle ... 2(a + b)
Perimeter of square = 4a
Perimeter of triangle = b + 2√[(1/2b)^2 + h^2] = b + 2√[(1/4)b^2 + h^2]
Perimeter of parallelogam = 2[ b + side length] ....this is all we can do on this one, rosala
Perimeter of circle 2 * pi * b
P.S. - If the triangle is equilateral.....then Anonymous' answer is correct......we're not told if it is or not.....!!!
Perimeter rectangle 2a +2b
Square 4a
Triangle 3b (assuming equilateral)
Parrallelogram 2a + 2b (same as rectangle); there might be some argument about this since a is not given.
Circle 2pi *b
