Question

2. The perimeter of a rectangular field is 360 m and its breadth is 75 m. Find its length
3. The length and breadth of a rectangular field are in the ratio 5 : 4. If its perimeter is
108 m, find the dimensions of the field.​

Answer 1

Step-by-step explanation:

2. The length of the rectangular field is 105 m.

Step-by-step explanation:

Given :The perimeter of a rectangular field is 360 m and it's breadth is 75 m.

To Find :Find it's length

Solution:

Breadth = 75 m

Perimeter of rectangle = 2(Length +Breadth)2(Length+Breadth)

=2(Length + 75)2(Length+75)

We are given that the perimeter of rectangular field is 360 m .

So, 2(Length + 75)=3602(Length+75)=360

(Length + 75)=180(Length+75)=180

Length=180-75Length=180−75

Length=105Length=105

Hence the length of the rectangular field is 105 m.

Answer 2

Answer:

2) 105 m

3) Length: 30m ; Breadth: 24m

Step-by-step explanation:

2) Perimeter of field = 360m

2 (l+b) = 360

l+b = 360÷2

l+75 = 180m

LENGTH = (180- 75)

LENGTH. = 105m

3) LET LENGTH = 5x

BREADTH = 4x

Perimeter of field = 2(l+b)

108m. = 2(5x+4x)

108÷2. = 5x+4x

54m. = 9x

54÷9. = x

6m. = x

LENGTH: 5×6 = 30m

BREADTH: 4×6 = 24m
