Answer:
48
Step-by-step explanation:
l=3×b
l=3b
perimeter =2(l+b)
32=2l+2b
16=l+b
16=3b+b
16=4b
4 =b
then, l=3b=12
area =lb=12×4=48 cm^2

Answer:
Let the breadth=x
Length=3x
Perimeter=2(l+b)
32=2(3x+x)
32=6x+2x
32=8x
32/8=x
4cm=x
Length=3x
=3(4)
=12cm
Breadth=4cm
Area of rectangle=l*b
=12*4
=48cm^2
The area of rectangle is 48cm^2.
