Answer 1

Answer:

Step-by-step explanation:

A floor mat of dimensions 459cm and 355cm was cut into square shaped door mats and it was seen that a piece of 9cm by 5cm is left.  

To find : maximum length of door mat

Solution:

459   - 9   = 450

355 - 5  = 350

Lets find HCF of 450 & 350

450 = 2 * 3 * 3 * 5 * 5

350 = 2 *  5 * 5  * 7  

HCF = 5 * 5  = 25

maximum length of door mat  = 25 cm
