Question

The length of a rectangle is 5 times its breath and its perimeter is 24 units . Find the length of the rectangle.​

Answer 1

Answer:

Let breadth be=b

then length=5 times the breadth= 5b

perimeter=24 units

perimeter=2(l+b)

24=2(5b+b)

24/2=5b+b

12=6b

12/6=b

b=2 units

l=5*2=10 units

length=10 units

I hope this helps...Mark me as the brainliest if you understood this.

Answer 2

Question:-

The length of a rectangle is 5 times its breath and its perimeter is 24 units . Find the length of the rectangle.

Answer:-

• The length of Rectangle is 10 units

Solution:-

• Let the breadth be x
• Then, The length is 5x
• Perimeter = 24 units

$\mathfrak{ \huge{ \purple{ \underline{ \underline{ \pink{ perimeter = 2(l + b)}}}}}}$

$\large{ \tt : \implies \: \: \: \: \:2(x + 5x) = 24}$

$\large{ \tt : \implies \: \: \: \: \:6x = \frac{24}{2} }$

$\large{ \tt : \implies \: \: \: \: \:6x = 12}$

$\large{ \tt : \implies \: \: \: \: \:x = \frac{12}{6} }$

$\large{ \tt : \implies \: \: \: \: \:x = 2 \: units}$

• The value of x is 2 units

Hence,

• Length = 5x = 5×2 = 10 units
