Answer 1

Answer:

square and rectangular have same perimeters

first find square plot

formula of square is 4*side

4*64 equalto 256

perimeter of square equalto perimeter of rectangular plot

256 equalto 256

now we find the breadth of rectangular plot

perimeter of rectangular plot equalto 2(l+b)

256 equalto 2(70+x)

256/2 equalto (70+x)

128 equalto 70+x

x equalto 128-70

x equalto 58
