Question

In a rectangle length is 3 more than twice of its breadth. Its perimeter is 36cm. What will be the length and breadth

Answer 1

Answer:

length = 13cm

breadth = 5cm

Step-by-step explanation:

let the breadth be xcm

therefore length is 3 more than 2 times breadth

= 2x +3

therefore the equation

p = 2(l + b)

36 = 2(2x + 3 + x)

36 = 2(3x + 3)

36 = 6x + 6

36 - 6 = 6x

30 = 6x

30/6 = x

5 = x

therefore breadth = 5cm

length = 2(5) + 3  = 13 cm
