I need help ASAP please

Answer 1

The perimeter is 35 units

Explanation:

Given

The attached shape

Required

The perimeter of the shape

From the shape, we have:

`AB = 11`

`AD = 8`

`BD = AD = 8` --- sides of an isosceles

Also:

`BC = DC = BD = 8` --- sides of an equilateral

So, the perimeter (P) is:

`P = AB + BC + DC + AD`

`P = 11 + 8 + 8 + 8`

`P = 35`

Properties of Isosceles triangles

2 sides are equal

2 angles are equal

Properties of equilateral triangles

All sides are equal

All angles are equal
