Answer:
A quadrilateral is a polygon with four sides.
Practicly anything with 4 sides like square, Rectangle ,and rhombas
Im sorry if i didn't answer your question but i did not get what you were saying but here is an image that can maybe help you
48 mm long
Since a square has all equal sides, it will be 12mm for all sides
Perimeter = L (Length) + W (Width) + L + W
(In this case since it’s a 2D shape)
12 + 12 + 12 + 12 = 48
Hope this helped :)
Using pythagoras a^2 + b^2 = c^2
8^2 + 3^2 = c^2
64 + 9 = 73
The square root of 73 is 8.54
So the length of the diagonals are 8.54cm
The side length is 7 because 7*7*7 is 343 cm3
