A tent is in the shape of a triangular prism, with a height of 120cm. The width across the base of the door is 1m and the tent is 2.3m long. Find the length of each sloping side, in metres. Then find the area of fabric used in construction of the sloping rectangles which form the sides.
The best thing to do here is to draw a diagram including all of the information you have been given, and see what you can do. |dw:1345717454992:dw| Now, can you see a way to work out the length of the sloping sides using a particularly useful theorem?
yes i used pythagoras theorem to figure out the sloping sides but how do i figure out the area
Well, what do you get for the length of the sloping sides?
1.3m
Excellent. So now you have to find the area of the sloping rectangles. You know what the width and height of the rectangles are, do you know how to find the area of a rectangle?
1.3 x 2.3
Very good, also don't forget that you have two sloping sides so you will need to double your answer to find the amount of fabric used.
your a genius thank you so much for the help :)
Ha no worries, you did most of the work! Well done :)
could you help me figure out another question
