Answer 2

Answer:

The value of s is 17.7mm.

Step-by-step explanation:

Given that perimeter of a shape happens when all sides are add up together. So for this question :

$perimeter = 7 + 19.9 + s + s$

$perimeter = 26.9 + 2s$

Let perimeter = 62.3mm,

$62.3 = 26.9 + 2s$

$2s = 62.3 - 26.9$

$2s = 35.4$

$s = 35.4 \div 2$

$s = 17.7mm$
