Question

The length of a rectangular feild is thirce of its breadth if the perimeter of the feild is 300m. then find the length and breadth of the field
​

Answer 1

Step-by-step explanation:

The length of a rectangular field(l) is 300 m.

Step-by-step explanation:

Let breadth of a rectangular field(b) = x

The, length of a rectangular field(l) = 3x

To find, the length of the field = ?

We know that,

The perimeter of rectangle = 2(l + b)

⇒ 2(3x + x) = 800

⇒ 2(4x) = 800

⇒ 8x = 800

⇒ x=\dfrac{800}{8}=100x=

8

800

=100

∴ The length of a rectangular field(l) = 3 × 100 m = 300 m

Hence, the length of a rectangular field(l) is 300 m.

Answer 2

Answer:

Length = 3b

so,

2 (l + b) = 300

2 ( 3b + b ) = 300

4b = 75

b = 75/4 = 18.75m

Now, length = 3b = 3 × 18.75m = 56.24m

Length = 56.24m and Breadth = 18.75m
