Here's link to the
d. bc = 12 and ef = 16
we are given that δabc : δdef such that .
also, it is given that
so, from the options, we need that .
as, we can see that only option d gives the same ratio as i.e. .
hence, the possible lengths are bc = 12 and ef = 16.
so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.
a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.
the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
