Question

the length of a rectangle is three times its width, If it's perimeter is 16 CM, then find its length and width

Answer 1

Answer:

Step-by-step explanation:

let the breadth be x

length = 3x

p = 2 ( l + b )

16 = 2 ( 3x + x )

16 = 8x

x = 2

breadth = 2

length = 3 x 2 = 6

Answer 2

Answer:

Step-by-step explanation:

formula for perimeter of rectangle 2(l+b)

where l is length and b is breath/width

given: l=3b

ATTQ

2(3b+b)=16

8b=16

so b=2 cm

and l=3x2=6 cm
