Question

a rectangular park of area 88200 meter square has jogging track around it.if length of park is twice the width,find the length of track?

Answer 1

area=88200 m sq.

let breadty be x

then length is 2x

area=l*b

2x2= 88200

x2= 44100

x= 210 m

length= 420 m

Answer 2

Area of a rectangle = l×b, let L be 2b

88200 = 2b × b

2b² = 88200

b² = 44100

b = 210 m

l = 2b

l = 2(210)m

l = 420m
