So I just sat a paper and really want to know if I did this question right. There was a parallelogram looking like the image below. Then 60 degrees was labelled in the bottom right corner. The length was 17cm and the height was 8cm on the sloped left side. The question was work out the area in term of a root b.

because they could drop even lower..

the value of x is 28.2

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
