here is give that:-
Area:-285²
length:- 19cm
breadth:- B
as we know that breadth is not given in the question.
so, for finding the breadth we put B.
using formula:-
area of rectangle is :- (L×B)
➪ breadth= area/length
➪ B=285/19
➪ B= 15
hence, we find that the breadth of the rectangle
now find the area of the rectangle
area=l×b
= L= 19 CM
= B= 15 CM
➪19×15
= 285
hence,proved
