b ² = 144
b = √144 = 12
Perimeter = 15 + 9 + 12 = 36 inches
Step-by-step explanation:
Step-by-step explanation:

Using a system of equations, it is found that Ajay is 25 years old today.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Wale was twice as old as Ajay 10 years back, hence:



Wale will be 40 years old in 10 years, hence:


Then, Ajay's present age is found as follows.
