The value of y that ensures the pool is a rectangle is 3. Option D
<h3>How to determine the value</h3>
The formula for perimeter of a rectangle is expressed as;
Perimeter = 2 ( length + width)
It is important to note that parallel sides of a rectangle are congruent, that is, they are equal.
Given the sides as;
5y + 6 = 8y -3
collect like terms
5y - 8y = -3 - 6
-3y = -9
Make 'y' the subject
y = 3
Thus, the value of y that ensures the pool is a rectangle is 3. Option D

Answer:
B) 18
Step-by-step explanation:
Perimeter = 2 + 2 + 1 + 2 + 1 + 2 + 1 + 4 + 1 + 2
= 4 + 3 + 3 + 5 + 3
= 7 + 8 + 3
= 10 + 8
= 18
