Question

the length of a rectangular Park is twice its breadth and its perimeter is 840 metre find the area of the park​

Answer 1

Answer:

39200 m^2

Step-by-step explanation:

Rectangular park !

Length = 2 x Breadth

Breadth = Let be x

Perimeter of rectangle = 2(l+b)

Putting the values.

840 = 2(2b+b)

840 = 4b + 2b

840 = 6b

b = 840 / 6

b = 140m

length will be :- 2 x b = 2x140 = 280m

Area of rectangle :- Length x Breadth

Putting the values !

280 x 140 = 39200m^2
