Answer:
184cm
Explanation:
to find the area of the triandles
4 times (half of 6 ) 3 = 12 divided by 2 = 6 + 6 ( because there are two right triangles making up one side ) so one side is 12cm add the other side 12 +12 = 24cm
To find the left and right sides mutipy length times width 10 x 5 = 50 add the oher side 50 + 50 = 100
To fide the bottom rectangle do the same thing but 10 x 6 = 60
so add everything together 24+100+60 = 184cm
