Question

If the length of a rectangle is 20m and its perimeter?

Answer 1

Answer:

this question is incorrect

the information given in the question is not enough to find the perimeter.

to find perimeter you need to provide length and breadth of the triangle.

if you mean square in place of the rectangle

area of square = 4a = 4×20

                                 = 80 $m^{2}$
