Question

the area of a square whose perimeter is equal to the perimeter of a rectangle with length 10cm and breadth 6cm is

Answer 1

perimeter of square =perimeter of rectangle
4*side=2( l+b)
side=2(10+6)/4
side=2*16/4
side=32/4
side=8
now area =8*8=64cm square

Answer 2

Perimeter of rectangle =2(l+b)

=2(10+6)

=2(16)

=32sqcm

Area of rectangle = lb

=10x6

=60sqcm

Perimeter of square =4a

60=4a

a=15

Area of square =a2

=15x15

225sqcm
