Answer:
length = 12 cm
Breadth = 4 cm
Step-by-step explanation:
Let length = l
breadth = [tex]\frac{1}{3}l[/tex]
Area of rectangle = 48 sq.cm
length * breadth = 48
[tex]l * \frac{1}{3}l = 48\\[/tex]
[tex]\frac{1}{3}l^{2}=48\\\\[/tex]
[tex]l^{2}=48*3\\\\l^{2}=144\\\\ l = \sqrt{144}\\\\[/tex]
l = 12 cm
breadth = [tex]\frac{1}{3}l = \frac{1}{3}*12 = 4 cm[/tex]
length = 12 cm
Breadth = 4 cm
