Two sides of an isosceles triangle measure 6 and 10. the perimeter of the triangle could be
a. 26 or 21
b. 12 or 20
c. 22 or 23
d. 26 or 22

both equations and proportions are better.

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.
