Question

length of rectangular plot is twice its breadth and the perimeter is 1200m. find its area

Answer 1

let the breadth be x cmand length is 2xcm

according to question

2(x+2x)=1200

3x=600

x=200

length=400cm

breadth=200cm

area =l×b

=200×400cm²

=80000cm²

hence area of rectangle is 80000cm².

Answer 2

Answer:

80000 m²

Step-by-step explanation:

Let be the breadth = x

if the length of rectangle is twice of breadth, So, it will be 2x.

Now,

A / Q

perimeter of rectangle = 2 ( L + B )

1200m = 2 ( 2x + x )

= 1200m = 2 × 3x

= 3x = 1200 / 2

= 600

= x = 600 / 3

= 200 m

So , breadth = 200

and the length = 2x m

= 2 × 200

= 400 m

Now,

Area of rectangle = L × B

= 400 × 200

= 80000m ²
