Question

please help me friends and I am going to mark us brain list.solve this question in the full method for example steps of divide then suppose my number is 131 divided by 2 so have you done it that

Answer 1

Peremeter=2(l+b)
131=2(l+25.5)
131/2=(L+25.5)
65.5-25.5=l
l=40

Answer 2

$\huge\bold\green{Solution : \longrightarrow}$

For the rectangle

Perimeter = 131 cm

Width (B) = 25.5 cm

Let the length be L cm.

We know that

Perimeter of rectangle = 2(L + B)

$\mathsf{ = > 131 = 2(L + 25.5)}$

$\mathsf{ = > 131 = 2L + 51}$

$\mathsf{= > 131 - 51 = 2L}$

$\mathsf{= > 80 = 2L}$

$\mathsf{ = > L= \frac{80}{2}} \\ \\ \mathsf{= > L = 40}$

•°• The length of the rectangle is 40cm.
