# In Exercises 1 to 8, find the perimeter of each polygon. ▱ A B C D with A B ¯   ≅ B C ¯     d 1 = 4   m   d 2 = 10   m

To determine

To Find:

Perimeter of ABCD.

Explanation

Formula Used:

The perimeter of a polygon is the sum of the lengths of all sides of the polygon.

The area A of a rhombus whose diagonals has lengths d1 and d2 is given by A=12d1d2.

The area A of a rhombus whose sides 'a' are known is given by A=a2.

Calculation:

It is given that AB¯=BC¯, d1=6 m and d2=8 m.

As AB¯=BC¯ and it is given as a parallelogram, all sides must be in equal length.

In rhombus, opposite sides are parallel and all sides are in equal length
