*think
ganeshie8 (ganeshie8):
nopes, forget about EH for now pls :)
first see that EF = 45, and its corresponding side AB = 5
ganeshie8 (ganeshie8):
45 is how many times bigger than 5 ?

YEs :) so the big quadrilateral perimeter also wub be 9 times the smaller quadrilateral
ganeshie8 (ganeshie8):
so we simply do this :-
1) find perimeter of small quadrilateral
2) multiply it wid 9
OpenStudy (anonymous):
the perimeter is 16 ..so 16x9 =144
ganeshie8 (ganeshie8):
Perfect ! good work :)

q simply says that, Jovan constructed a triangle
ganeshie8 (ganeshie8):
its actually 3rd option.
cuz, we dont knw wat type of triangle he drew. so we cant conclude, if he drew an acute triangle or not
ganeshie8 (ganeshie8):
does that make sense ? :)
OpenStudy (anonymous):
