Answer:
length = 18cm and breadth= 6cm
Step-by-step explanation:
let length= 3x and breadth be x
perimeter=48cm
perimeter of rectangle =2(length + breadth)
48=2(3x+x)
48=2×4x
48/2=4x
24/4=x
x=6cm
x=breadth=6cm
AND
length=3x
length=3×6
length=18cm
Let the breadth of the given rectangle be x cm then its length will be 3x cm.
Perimeter of the rectangle = 2 (length+breadth)
40=2(x+3x)
40=8x
∴x=5
∴ length of rectangle =(5×3) cm
=15 cm
breadth of rectangle =(5×1) cm
=5 cm
∴The length and width of the rectangle is 15 cm
