Question

the perimeter of rectangle is 40cm .the length of rectangle is 2cm more than twice of its breadth then find the length and breadth​

Answer 1

Answer:

Let the breadth of the rectangle be x cm

so, the length is (2x + 2) cm

so, according to the question,

$2(x + 2x + 2) = 40$

$2(3x + 2) = 40$

$3x + 2 = \frac{40}{2}$

$3x + 2 = 20$

$3x = 20 - 2$

$3x = 18$

$x = \frac{18}{3}$

$x = 6$

so the breadth is 6 cm and the length is

(2 x 6 + 2) cm = (12 + 2) cm = 14 cm

hope it helps
