I need help doing this, it is my last question on this and I need help with it

290 inches squared

Step-by-step explanation:  Break it down into easier potions such as...

18 x 7=126

13 x 4=52

16 x 7=112

Then add them for total area.

I’m not sure if I’m correct but I think it’s 290 inches

Step 1. Multiply 7 by 27= 189
Step 2. Add the 4 in and 7 in to find that side length which is 11.
Step 3. Multiply 6 by 11= 66
Step 4 multiply 5 by 7= 35
Step 5. Add those up
Answer is 290 inches.

I'm pretty sure it's D.40 because it's the biggest number and 6+13+17 is only a bit bigger than 24. Also, all the numbers add up to 60 and 27 is only a bit less than 50% of 60
