Question

the area of square and rectangle are equal. the perimeter of the square 420 cm.the length of the rectangle is 125 cm . calculate the breadth rectangle and area of square

Answer 1

the area of square is side *side
side =perimeter/4
420/4=105cm
area=105*105=11,025
breadth of rectangle=area/length
11025/25=88.2cm

Answer 2

perimeter of square = 4×side of square = 420
side of square = 420÷4=105
area of square = side ^2 = 105 ^2= 11025
perimeter of rectangle = 420
breadth of rectangle = 85
area of rectangle = 85×125=10625
