Question

ratio of length and breadth of a rectangle is 3 : 2.if the length of rectangle is 5 M more than the breadth find the perimeter of the rectangle

Answer 1

Answer :

50 m

Step-by-step explanation :

Let the length and breadth of a rectangle be 3x and 2x respectively.

According to the question ;

3x - 2x = 5

⇒ x = 5

Length of rectangle = 3x = 3*5 = 15 m

Breadth of rectangle = 2x = 2*5 = 10 m

Now,

Perimeter of rectangle = 2 ( l + b )

⇒ 2 ( 15 + 10 )

⇒ 2 * 25

⇒ 50 m

Hence, the perimeter of rectange is 50m.

Answer 2

HEY MATE!! HERE'S UR ANSWER!!! ^_^
____________________________

The ratio of length and the breadth of the rectangle is 3:2.

$let \: x \: be \: the \: common \: multiple \\ of \: this \: ratio$

Then,
$length \: of \: the \: rectangle \: = 3x \\ breadth \: of \: the \: rectangle = 2x$

Length of the rectangle is 5m more than the breadth,

$3x - 2x = 5$

$x = 5$

$length \: of \: the \: rectangle \: = 3x = 3 \times 5 = 15m \\ \\ breadth \: of \: the \: rectangle = 2x = 2 \times 5 = 10m$

As we have now got the length and the breadth of the rectangle, we can now hereby easily get the perimeter of the rectangle using the formula.

$perimeter \: of \: the \: rectangle = 2(l + b)$

$perimeter \: of \: the \:rectngle = 2(15m+ 10m)$

$perimeter \: of \: the \: rectangle = 2 \times 25$

$perimeter \: of \: the \: rectangle = 50m$


Therefore,
Length of the rectangle=15m,

breadth of the rectangle=10m

Ans:the perimeter of the rectangle =50m.
