Given PQRS is a square, solve for x.

Set the equation up like this (6x - 21) = 45

Add 21 to each side

6x = 66

Now divide each side by 6

x = 11

Hope this helps!

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.
