Answer 1

Answer:

(20a - 36b) metres

Step-by-step explanation:

$Side=(5a - 9b) m$

$Perimeter=4$ × $Side$

                  $= 4 (5a-9b)$

                  $=(20a-36b) m$                        

Answer 2

Answer:

20a - 36b

Step-by-step explanation:

5a - 9b is the measure of a side of the square.

So lets assume that 5a - 9b x 4 equals the perimeter

So 20a - 36b is the answer for this question
