Answer Verified Verified
Hint: Let the height equal to some variable. Then, follow the question.

Complete step-by-step answer:

Let the height is $h$.
It’s given to us that; length is 5 times the height.
So, the length, $l = 5h$
Also, breadth is 10 cm less than length.
So, breadth $b = l - 10$
Now, $l = 5h$
$\Rightarrow$ $b=5h - 10$

Hence the required answer is $l = 5h$ and $b = 5h - 10$.

Note: In such times of questions, it’s always recommended to let something in at the beginning of the solution and then follow the question word by word.
