Question

The perimeter of a rectangle is 20metres and one of its side is 4m. How many meter is the other side?​

Answer 1

Answer:

6m Ans

Explanation:-

Let assume that the length of rectangle is 4m then we need to find its breadth b

Therefore Perimeter of Rectangle = 2 × (l + b)

20m = 2 × (4m + b)

20m = 8m + 2b

20m - 8m = 2b

12m = 2b

b = 6m

Therefore other side is of 6m.

I hope you understand it.

Thanks and have a wonderful day.

Answer 2

___________________________________________

TO FIND:-

• Other side of Rectangle

SOLUTION:-

• Perimeter of Rectangle = 20m
• One Side [Breadth of Rectangle] = 4m

As we know,

$\boxed {\purple { \sf{Perimeter = 2(l + b)}}}$

Where,

• l = Length of Rectangle
• b = Breadth of Rectangle

According to the Question,

:$\implies \sf{2(4 + l) = 20}$

:$\implies \sf{4 + l = \frac{20}{2} }$

:$\implies \sf{4 + l = 10}$

:$\implies \sf{l = 10 - 4}$

:$\implies \sf \red{l = 6}$

$\sf \pink{Hence,}$

• $\sf \pink{The \: Other \: Side \: of \: Rectangle \: is \: 6m.}$
