Question

The length and breadth of a rectangular field are in the ratio 5:3 if it's perimeter is 128m find the dimensions of the field.

Answer 1

Answer:

40,24

Step-by-step explanation:

the perimeter of rectangle =2(l+b)=128

=2(5+3)=128

=2(8)=128

=16=128

=128/16

=8

the dimensions of the fields =5*8=40

=3*8=24

Answer 2

Answer:

The Length is 40 m and Breadth is 24 m.

Step-by-step explanation:

Given :

Ratio of Length to Breadth = 5 : 3

Perimeter = 128 m

To find :

Its dimensions

Solution :

Let the -

• Length be 5y
• Breadth be 3y

★ Perimeter = 2(Length + Breadth)

⇒ 128 = 2(5y + 3y)

⇒ 128 = 10y + 6y

⇒ 128 = 16y

⇒ y = 128/16

⇒ y = 8

★ Length = 5(8) = 40 m

★ Breadth = 3(8) = 24 m

$\therefore$ The Length is 40 m and Breadth is 24 m.
