Question

The perimeter of a rectangle is 40m and breadth is 6mthen what is the length of the rectangle
please give me answer fast and with explanation ​

Answer 1

addition of length and breadth = perimetre / 2

x + 6 = 20

x = 20 - 6

= 14

so the length is 14m

pls mark me brainliest dear brother or sister

Answer 2

Answer:

Given:-

The perimeter of a rectangle is 40m and breadth is 6m then what is the length of the rectangle?

To Find:-

The length of the rectangle.

Note:-

●》Perimeter of the rectangle = 2 × ( Length + Breadth ), when it is transposed; Length = $\frac{Perimeter}{2} - Breadth$

Solution:-

$\huge\red{Perimeter \ \ of \ \ the \ \ rectangle = 40m, Breadth = 6m, Length = ?}$

☆ According to note first point~

▪︎$Length = \frac{Perimeter}{2} - Breadth$

▪︎$Length = \frac{40m}{2} - 6m$

▪︎$Length = 20m - 6m$

☆ After doing calculations~

▪︎$Length = 14m$

$\huge\pink{Length = 14m}$

Checking:-

♤ Let's check that perimeter of rectangle = 2 × ( Length + Breadth ) or not.

• $Perimeter \ \ of \ \ the \ \ rectangle = 2 × ( Length + Breadth ) \ \ ?$

• $40m = 2 × ( 14m + 6m ) \ \ ?$

• $40m = 2 × 20m \ \ ?$

• $40m = 40m \ \ ?$

♤ Yes!

$\huge\pink{Hence, Proved \ \ that \ \ Length = 14m}$

Answer:-

Hence, the value of Length = 14m.
