The solutions to the questions are
- The number we are using is 5
- The perfect square number closest to the area is 1024
- The estimated side length is 32
<h3>What are areas?</h3>
The area of a shape is the amount of space on the shape
For most regular quadrilaterals, you multiply the side lengths to determine the area
<h3>The number to use</h3>
The area expression is given as
Area = ▢ × 102 + ▢ × 101 + 6
From the question, we can use any number
However, this number must be positive
Assume the number is 5
So, we have
Area = 5 × 102 + 5 × 101 + 6
<h3>The perfect square number closest to the result</h3>
In (a), we have:
Area = 5 × 102 + 5 × 101 + 6
Evaluate
Area = 1021
The perfect square number closest to this is
Closest = 1024
<h3>The estimated side length</h3>
In (b), we have
Closest = 1024
Rewrite as
Area = 1024
Take the square roots
Length = 32
