Hello!
My final exam is approaching and as I was going over some problems for review I stumbled upon a few that gave me a significant amount of trouble.
The first reads: Find the area of rhombus PQRS to the nearest tenth. TR=12m I found that each side measured 13 and I began to set up the area formula (A=1/2xd1xd2) however I cannot seem to figure out what the other diagonal is...
The second reads: Find the area of a regular hexagon with perimeter of 72 inches. Round to the nearest tenth. My work is shown in the picture however I am unclear as to how to discover if the triangle is 45, 45, 90 or 30, 60, 90.
Thank you so much!
