Question

Perimeter of rectangle is 28 cm and its breadth 4 cm find the length of the rectangle

Answer 1

let length be a and breadth be b.

perimeter= 2(a+b)

28= 2(a+4)

a+4 = 28/2

a= 14-4

a= 10

please mark it as brainliest,..

Answer 2

$\sf{Perimeter \ of \ rectangle = 28 \ cm \qquad (Given)}$

$\sf{Breadth \ of \ rectangle = 4 \ cm \qquad (Given)}$

${\boxed{\sf{Perimeter = 2(Length + Breadth)}}}$

$\sf{Putting \ values, \ we \ get}$

$\sf{28 = 2(Length + 4)}$

$\sf{ {\dfrac{28}{2}} = Length + 4}$

$\sf{14 = Length + 4}$

$\sf{Length = 14 - 4}$

$\sf{Length = 10}$

$\therefore$ $\sf\red{ \ The \ length \ of \ rectangle \ is \ 10 \ cm.}$
