Question

The lenght of a rectangle is 1 more than twice its breadth. a) If breadth is x cm what is its length? b) If the perimeter of a rectangle is 50 cm, find the length and breadth of the rectangle​

Answer 1

Answer:

ஃ, a) Length = ( 2x + 1 ) cm

b) Breadth = 8 cm

Length = 2x + 1 cm = 2 × 8 + 1 = 17 cm

Step-by-step explanation:

a) Given, breadth = x cm

Length = ( 2x + 1 ) cm

b) Perimeter = 2 ( L + B )

50 cm = 2 ( x cm + ( 2x + 1 ) cm )

2 ( x + 2x + 1 ) = 50

2 ( 3x + 1 ) = 50

6x + 2 = 50

6x = 50 - 2 = 48

$\sf x = \frac{\cancel{48}}{\cancel{6}} = 8 \: cm$
