Ratio Of Area of Rectangle To Area Of Square Is 1:4, Ratio Of Perimeter Of Rectangle To Perimeter Of Square Is 1:2. If The Length Is 5 cm Then Find The Area Of Square

One side of Rectangle =5, given

Other side of Rectangle  = x                                                                                         

Side of Square =y             

Area of Rectangle =5*x

Area of Square = y2

5x:y2  =1:4

y2 =20x


Perimeter Of Rectangle= 2 (5+x)

Perimeter Of Square = 4y

2 (5+x) : 4y=1:2  ,


Squaring both side

25+x2 +10x =y2

25+x2 +10x =20x

x2 -10x+25=0


y2=20x =20*5 =100

Area = y2   =100
