Question

the area of a rectangular sheet of aluminum is 400cm . if the breadth of the sheet is 16 cm., find its length

Answer 1

Let it's length be X.
area =400cmsq. breadth =16cm
we know that the area of rectangle =length×breadth
so, l×b=400
X×16=400
X=400÷16
X=25m
so the length is 25m
hope it helped

Answer 2

$<b>$


$\bold{ \fbox{area \: of \: \: rectangle = length \times breadth}}$



We have:-

Breadth of sheet=)16cm

Area of sheet=)400 cm

ACCORDING TO THE FORMULA


Area of Rectangle Sheet=Length x Breadth

$\bold{ \huge{ \cancel{400 = length \times {\cancel{16}}}}}$


$\bold{ \huge{length = 25cm}}$
