Answer: x = 16.5
Step-by-Step Explanation:
Length (l) = (x) cm
Breadth (b) = (x - 4) cm
Perimeter = 2(l + b) = 58 cm
Substituting values of ‘l’ and ‘b’ :-
=> 2(l + b) = 58
= 2(x + x - 4) = 58
= 2(2x - 4) = 58
= 4x - 8 = 58
= 4x = 58 + 8 = 66
=> x = 66/4 = 16.5
Therefore, x = 16.5
Finding ‘l’ and ‘b’ :-
l = x
=> l = 16.5 cm
b = x - 4
b = 16.5 - 4
=> b = 12.5 cm
Length (l) = 16.5 cm
Breadth (b) = 12.5 cm
