Question

11-13 answers plssssss

Answer 1

11. The perimeter of A is 16 because 2(5 + 3) = 16.
 The perimeter of B is 44 because 2(11+11) = 44. 
 The perimeter of C is 16 because 2(4 + 4) = 16.
 The perimeter of D is 14 because 2(3 + 4) = 14. 
That means that the perimeter of B is the most since 44 is more than 16 & 14. 

12. Figure C has an area of 108 cm² because 9 x 12 = 108. 

13. Figure A has an area of 40 square ft. The main mass is 8 x 4, which is 32. 
There are 2 smaller squares on the sides, each 2 x 2, which is 8 for both. 
32 + 8 = 40 total square feet. 

Hope this helps!
