Need help with find the surface area

9514 1404 393

  228 square inches

Step-by-step explanation:

The two "wings" extend up 4 inches and down 4 inches below the main horizontal set of rectangles. The width of the left column of rectangles is 6 in, so the area of that column is ...

  6 in × (4 in + 9 in + 4 in) = 102 in^2

The three rectangles on the right have a total width of ...

  (4 in + 6 in + 4 in) = 14 in

and their height is 9 in. The area of those three rectangles is ...

  (9 in)(14 in) = 126 in^2

So, the total surface area is ...

  102 in^2 +126 in^2 = 228 in^2

The surface area is 228 square inches.

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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.
