Question

The perimeter of a rectangular field is 1.2km and its length is twice its breadth. Determine the areaof the field.

Answer 1

Answer:

0.08 sq km

Step-by-step explanation:

l =x

w =x/2

{x+(x/2)}2 =1200m

3x =1200

x =400  thus,

l =400m or 0.4km  and

w =200m or 0.2km   thus area of the field ;

0.2km * 0.4km = 0.08km2
