Question

Length of a rectangle is 3 times its breadth. What are its length and breadth if its area is 432 sq m?​

Answer 1

Let the breadth of rectangular field be b m
By given, its length= 3b m
Now area of the field= 432 sq m
l×b=432
3b×b=432
3b^2 = 432
b^2 =144
b=12m
l=3b=3(12)
l= 36 m
Length =36m ;breadth= 12m
