Answer 1

It's D

Explanation:

Answer 2

The correct answer option is b. Perimeter = 19.2 units, Area = 22 units
`^2`.

Explanation:

We are given a pentagon ABDEC and we are to find its perimeter.

From the given figure, we can clearly see that the pentagon can be divided into two shapes, a square and a triangle. One side of each of these shapes will be excluded from the perimeter.

Distance of AB =
`√((4-1)^2+(6-4)^2) = √(13) =3.6`

The length of AB and AC are same and the BD, DE and CE are same (4 units).

Perimeter of pentagon ABDEC = 4 + 4 + 4 + 3.6 + 3.6 = 19.2 units

Area = (area of ΔABC) + (area of square BDEC)

=
`((1)/(2) *4*3)+(4*4)`

= 22 units
`^2`
