Answer:
2 ( k + ( 2k +4)) = 50 cm is the required equation.
Width of rectangle = 7 cm, Length of rectangle = 18 cm
Step-by-step explanation:
The perimeter of the rectangle = 50 cm
Le the width of the rectangle = k cm
⇒The length of the rectangle = (2k + 4) cm
Now, PERIMETER OF THE RECTANGLE = 2( LENGTH WIDTH)
⇒ 2 ( k + ( 2k +4)) = 50 cm
or, 2( 3k+ 4) = 50
⇒ 6k + 8 = 50
or, 6k = 50 - 8 = 42
or, k = 42/6 = 7
⇒ k = 7 cm
Hence, the width of the rectangle = k = 7 cm
and the length of the rectangle = (2k +4) = 2(7) + 4 = 18 cm
