A rectangle has a perimeter of 52 cm and an area of 144 square cm. Find its length and width if they are in whole numbers.
Answers
The length of the rectangle will be 18 cm.
The width of the rectangle will be 28 cm.
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The perimeter of rectangle = 52 cm
An Area of a rectangle = 144 cm²
Let the length of the rectangle = l
The width of the rectangle = b
So, We get;
⇒ 2 (l + b) = 52
⇒ l + b = 26 ..(i)
And, l x b = 144 ..(ii)
Since, (l - b)² = (l + b)² - 4lb
= (26)² - 4 × 144
= 676 - 576
= 100
⇒ l - b = √100
⇒ l - b = 10 ..(iii)
Solve equation (i) and (iii), we get;
⇒ l = 18 cm
⇒ b = 28 cm
Thus, The length of the rectangle will be 18 cm.
The width of the rectangle will be 28 cm.

The dimensions of length can be measured using a ruler, and the angle measurement can be made with the use of a protractor
The dimensions (calculated) of the figure are:
Angles formed at each intersection;
Angle A is approximately 97.125°
Angle B is approximately 53.6°
Angle C is approximately 26.6°
Lengths of the straight sides;
Side AB is approximately 3.6
Side BC is 8
Side AC is approximately 6.7

The reason the above values are correct is as follows:
Question: The coordinates of the points A, B, and C, obtained from a similar question online are; A(3, 4), B(1, 1), and C(9, 1)
Please find attached the diagram of the tree paths that intersect at the points A, B, and C
The required parameter:
To measure and record the angle formed at each intersection
The angles can be measured using a protractor, however, by calculation, we have;
The length of AB = √((3 - 1)² + (4 - 1)²) = √13 ≈ 3.6
The length of BC = √((9 - 1)² + (1 - 1)²) = 8
The length of AC = √((9 - 3)² + (1 - 4)²) = √45 = 3·√5 ≈ 6.7
By cosine rule, we have;
Therefore, the angles formed at each intersection are;
Angle A ≈ 97.125°
Angle B ≈ 53.6°
Angle C ≈ 26.6°
The lengths of the straight side are;
Side AB ≈ 3.6
Side BC = 8
Side AC ≈ 6.7

Start with a triangle:
area is base side * height / 2 -> 4 * 3 / 2 = 6
The other triangle has the same area: 6
First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21
Now simply add all this together: 6+6+35+28+21 = 96
