Question

9. The length of a rectangular field is twice its breadth. If the area of the field is 11250 m2, find its
perimeter.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

ok,

sol:

l = 2b......{Given}

Area of rectangular field = l × b

11250 = 2b x b

11250 = 2b²

b² = 11250/ 2

b² = 5625

b = √(5,625)

breadth = 75.......(1)

Now,

Area of rectangle = l × b

11250 = l × 75

l = 11250 / 7

length = 150.......(2)

Now,

Perimeter of rectangular field = 2(l + b)

= 2( 150 + 75)

= 2( 225)

= 450m

Ans. The perimeter of rectangular field = 450m.
