Question

out of a 100cm long wore Ali made a right angled quadirlateral .what can be the maximum area of the quadrilaterial ?explain with figure

Answer 1

let s be the side of the quadrilateral and a be its area
quadrilateral=square
perimeter=100cm
perimeter of a square=4s
                            100=4s
                         100/4=s
                              25=s
                 therefore s=25
area of a square=s^2
                        a=s^2
                        a=25*25
                        a=625

Therefore the largest area is 625cm^2
