A² + b² = c²
c² = 4² + 6.5²
c² = 58.25
c = 7.63
Perimeter = 4 + 6.5 + 7.63 = 18.13 units.
Perimeter after the increase in scale = 18.13 x 4 = 72.52 units.
Answer: 72.52 units
1) Tan45 = 1
2) Sin70 = 0.9397
3) Cos30 = 0.8660
4) Cos20 = 0.9397

In order to make a 3-dimensional object into a 4-dimensional object, it's important to draw the 4-dimensional shape in a way that gives the illusion of the 3-dimensional object.
<h3>How to illustrate the information?</h3>
It should be noted that shapes play an important part in geometry.
Here, to make a 3-dimensional object into a 4-dimensional object, it's important to draw the 4-dimensional shape in a way that gives the illusion of the 3-dimensional object.
Also, it should be noted that a 4D tesseract can be used to project the image.
