QUESTION
:- IF THE LENGTH of a rectangle is 20 cm more than its breadth. if the perimeter is 100 cm find the dimension of the rectangle ????
ANSWER:-
BREADTH =X=15 CM
LENGTH =X+20=35CM
EXPLANATION :-
▶let the breadth be x
▶length = x+20 cm
▶perimeter =2 (l+b)
= 2 (x+20 +x)
=2 (2x+20)
=4x+40
ACCORDING TO PROBLEM
PERIMETER =100 CM
4x+40=100
4x=100-40
4x=60
x=60/4
x = 15 cm
therefore
BREADTH =X=15 CM
LENGTH =X+20=35CM
