Question

. The ratio of the length and breadth of a plot is
3 : 2. If the breadth is 40 m less than the
length, what is the perimeter of the plot?​

Answer 1

Answer:

400

Step-by-step explanation:

let the length , breadth = 3x,2x

so 2x + 40 = 3x

hence X= 40

therefore Length = 3 multiplied by 40 = 120

Breadth = 2 multiplied by 40 = 80

Perimeter of Rectangle = 2( l + b)

= 2( 120 + 80 )

= 2(200)

= 400

Answer 2

Answer:

$\huge\rm\red{❥AnsWer:}$

• ratio of length and breadth = 3:2

• Let the length be 3x

• let the breadth be 2x

• breadth is 40 less than length

• equation formed ➡️ 3x - 40 = 2x

$\bf\pink{3x-40=2x}$

➡️ 3x = 2x + 40

➡️ 3x - 2x = 40

➡️ x = 40

Therefore ,

Length = 3x

= 3× 40

= 120 m

Breadth = 2x

= 2×40

= 80 m

Perimeter = 2×(length + breadth )

= 2×(120+80)

= 2× 200 m

= 400 m²
