Question

The length of rectangle is thrice its breadth and its perimeter is 48cm. Find length and breadth of rectangle.

with explanation​

Answer 1

Answer:

Step-by-step explanation:

Given,

Let Breath of the rectangle be 'x'

Length=thrice its breath=3x

Perimeter of the reactangle: 48cm

We know that perimenter of the rectangle is: 2(Length+Breadth)

so, our equation will be:

2(l+b)=48

2(3x+x)=48  

2(4x)=48

8x=48

x=48/8 {sending 8 to the other side}

x=6cm#

Therefore:

                    Length = 3x = 3(6) = 18cm

                    Breadth = x = 6cm

Thank you,

Answer 2

$\huge\bold{Given:-}$

• The length of rectangle is thrice its breadth and its perimeter is 48cm. Find length and breadth of rectangle.

$\huge\bold{To \: Find:-}$

• Length and breadth.

$\huge\bold{Solution:-}$

Let the length be x.

$\huge\bold{Formula:-}$

2(L+B)

• So, $\implies$2(x+x3)=48

• $\implies$2×4x=48

• $\implies$8x=48

• $\implies$x=48/8

• $\implies$x=6

:.Breadth = 6cm

For Length:-

• $\implies$6×3

• $\implies$18

:.Breadth = 18cm

hope it helped!
