Dear student,
$L e t t h e b r e a d t h b e' x' l e n g t h = 4 x - 3 N o w w e k n o w p e r i m e t e r = 2 \times (L + B) \Rightarrow 94 = 2 \times (4 x - 3 + x) \Rightarrow \frac{94}{2} = 5 x - 3 \Rightarrow 47 = 5 x - 3 \Rightarrow 47 + 3 = 5 x \Rightarrow 50 = 5 x \Rightarrow x = 10 t h u s b r e a d t h o f r e c \tan g l e i s 10 m a n d b r e a d t h = 4 \times 10 - 3 = 40 - 3 = 37 m$
