Answer 1

Answer:

Step-by-step explanation:

Question:-

The ratio between length and breadth of a rectangular field is 5: 3. If the length is 120 m, then breadth is

?

Given :-

• Let the ratio constant be x.
• So, length be 5x
• And breadth be 3x

To find:-

• Breadth, when length is 120

Concept:-

Ratio and Proportion

Let's do!

$5x=120$

$x=\dfrac{120}{5}$

$\rm{x = 24 \ m}$

We found x. Now , we can easily find the breadth.

breadth = 3x

=3 * 24

= 72 metre.

What if to find Area?

$\rm{Area = Length \times Breadth}$

Length = 5x = 5*24 = 120 m.

Now, applying all,

$= 120 \times 72$

$\implies 8640 \ m^2$

$\boxed{\bigstar \bf{A \ special \ vigil \ on \ units \ to \ be \ kept.}}$

Answer 2

Solution :

• Ratio of length and breadth = 5:4
• Measure of Length = 120m
• Breadth = ❓

${ \blue{ \mathscr{ \underline{Let : - }}}}$

Let the length be 5x and breadth be 3x

As the measure of Length is given

So,

5x = 120

x = 120/5

x = 24 m

⠀⠀⠀ Now we get the value of x ,

• Breadth = 3x

= 3 × 24

= 72m

Hence,

• Measure of Breadth is 72m .

⪼ Area of rectangle = l × b

⪼ Perimeter of rectangle = 2(l + b)

⪼ Length of rectangle = Area/Breadth

⪼ Breadth of rectangle = Area/length

⪼ Diagonal of rectangle = √l² + b²
