Question

Hello! Pls Solve This Problem I'm Stuck Pls I Need It ASAP! ​

Answer 1

Ans (i) :

Perimeter = 54 cm

Length = x cm

Breadth = x + 6 cm

Perimeter of a rectangle = 2 ( l + b )

54 = 2 ( x + x + 6 )

54 / 2 = 2x + 6

2x + 6 = 27 ⇒ Equation

Ans (ii) :

2x + 6 = 27

2x = 27 - 6

2x = 21

x = 21 / 2 = 10.5

Length = x = 10.5 cm

Breadth = 10.5 + 6 = 16.5 cm

Answer 2

Answer:

2(x+x+6)=54

2(2x+6)=54

4x+12=54

4x=54-12

4x=42

x=42/4

x=11.5

Lenght=x+6=(11.5+6)cm=17.5cm

Breadth=x=11.5cm
