<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
Given Monique prefers the ratio of multiple-choice questions to essay questions to be 4:1, Therefore, we can write,
Multiple choice questions/ essay questions = 4/1,
If we multiply both the numerator and the denominator by 6, the ratio will be,
Multiple choice questions/ essay questions = 4/1 × 1
Multiple choice questions/ essay questions = (4/1) × (6/6)
Multiple choice questions/ essay questions = 24 / 6
Thus, Monique should choose the third option.

Answer:
The length of the side of the triangles are;
First side = 38 ft
Second side = 19 ft
Third side =24 ft
Step-by-step explanation:
To solve the question we are going to take;
Second side is x ft
Since, the first side is 2 times the second side then;
First side of the triangle is 2x ft
Since the third side is 5 ft less than the second side, then;
The third side is (x+5) ft
But, the perimeter of the triangle is 81 ft
Perimeter of a triangle is given by the sum of sides;
Therefore;
x + 2x +(x +5) = 81 ft
4x + 5 = 81
4x = 76
x = 19 ft
Therefore;
Second side = 19 ft
First side = 38 ft
Third side = 24 ft
