Please help me I need help with this problem for some reason im not able to get it

ok

step-by-step explanation:

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.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
