The answer is b

The perimeter of a rectangle is 2(l + w) so in this case, it is 2(15 + 9) and that is equal to 48. But so at c and d. So u need to multiply the width by 2 (9*2=18) and then you’ll see that 18-3=15. And therefore, the length is -5 and the width is 9

mylen [45]

Answer:

6 x 4 = 24, 24 divided by 2 = 12(area of 1 triangle)

12 x 2(two triangles) = 24

5 x 6 = 30(area of 1 slanted rectangle)

30 x 2(two rectangles) = 60

6 x 6 = 36(area of bottom square)

Add all given AREAS:

24 + 60 + 60 = 144 mm2 is your answer.
