Answer:
The perimeter is 35 units
Step-by-step explanation:
Given
The attached shape
Required
The perimeter of the shape
From the shape, we have:
[tex]AB = 11[/tex]
[tex]AD = 8[/tex]
[tex]BD = AD = 8[/tex] --- sides of an isosceles
Also:
[tex]BC = DC = BD = 8[/tex] --- sides of an equilateral
So, the perimeter (P) is:
[tex]P = AB + BC + DC + AD[/tex]
[tex]P = 11 + 8 + 8 + 8[/tex]
[tex]P = 35[/tex]
Properties of Isosceles triangles
2 sides are equal
2 angles are equal
Properties of equilateral triangles
All sides are equal
All angles are equal
