Answer:
Step-by-step explanation:
<u>Perimeter is:</u>
- P = 40 cm
- and
- P = 2x - 4 + 5x - 13 + x + 9 = 8x - 8
<u>Comparing the value:</u>
- 8x - 8 = 40
- 8x = 48
- x = 8 cm
<u>Are formula:</u>
<u>Replacing values:</u>
- A = 1/2(x + 9)(2x - 4)
- A = 1/2(8 + 9)(2*8 - 4) = 1/2*17*12 = 102 cm²
The answer is B. because if you take 4.20 and divide it by 3.5 you get 1.20
I think the answer is b because it make the most sense
The height would be 3 feet because it would be just tall enough to be waist level
