Answer 1

Answer:

Step-by-step explanation:

breadth of rectangle=x

Then length of the rectangle = 3x

Perimeter of the rectangle = 96cm

2(l+b) = 96m

X+3x = 48

x = 12cm

→Breadth of rectangle = 12cm

→Length of rectangle = 3×12=36cm

Answer 2

_____3x____ Let the width be x
| | metre and the
x | |x length be 3x
|__________| metre.
3x
The perimeter of a rectangle =2(Length + Width)
Perimeter = 2(x + 3x)
96 = 2(4x)
96 = 8x
96/8 = x
12 metre = x



Breadth(Width) = x = 12m
Length = 36m
