Question

The perimeter of rectangular field 3/5 km.If the length of field is twice its width, find its area in sq metres

Answer 1

Answer:

20000 m²

Step-by-step explanation:

Define x:

Let the width be x

The length = 2x

Solve x:

Given that the perimeter is 3/5 km

Perimeter = 3/5 km = 3/5 x 1000 m = 600 m

2( Length + Width) = Perimeter

2(x + 2x) = 600

6x = 600

x = 100 m

Find the dimension:

Width = x = 100 m

Length = 2x = 2(100) = 200 m

Find the area:

Area = Length x Width

Area = 100 x 200 = 20000 m²

Answer: The area is 20000 m²
