Question

find the length if perimetar is 180 breadth 25​

Answer 1

Correct Question :

find the length if the perimeter of a rectangle is 180 and breadth is 25 .

Answer :

$\sf\pink{Given:}$

• Perimeter is 180 .

• breadth is 25 .

$\sf\pink{To\:find:}$

• length is ?

Explanation :

$\sf\pink{Perimeter\:of\: rectangle = 2( l + b)}$

$\longrightarrow\sf{ 180 = 2\times ( l + 25)}$

$\longrightarrow\sf{ 180 = 2l + 50}$

$\longrightarrow\sf{ 180 - 50 = 2 l}$

$\longrightarrow\sf{ 180 - 50 = 2 l}$

$\longrightarrow\sf{ l = \dfrac{130}{2}}$

$\longrightarrow\sf{ l = 65}$

• Therefore the length is 65 .

Answer 2

Answer:

l = 65

Step-by-step explanation:

p = 180

b = 25

p = 2 * (l + b )

180 = 2 * (l + 25)

= 180/2 = l + 25

= 90 = l + 25

= 90-25 = l

∴ 65 = l
