Question

2. The length of a rectangular plot of land is twice its breadth. If the perimeter of the plot be 180
meters then find its area​

Answer 1

HEY! UR ANSWER IS:

Let the breadth be, x

Length=  2x

Perimeter=180 m

Perimeter= 2(l+b)

180=2(2x+x)

180/2=3x

90=3x

90/3=x

x=30m {Breadth}

Length = 30*2 = 60 m

Area= l*b

A= 60*30

Area=1800 m²

HOPE THIS MAKES UR DAY BETTER!!

Answer 2

Answer:

let the breadth be x

length = 2x

perimeter = 2(l+b)

180 = 2(2x+x)

180 = 4x+ 2x

180 = 6x

x = 180/6

x = 30
