Answer:

  • 100 and 600

Step-by-step explanation:

Let the numbers be a and b.

<u>We have:</u>

  • a + b = 1600

and

  • 0.12a = 0.2b, simplified as b = 0.6a

<u>Substitute b into the first equation:</u>

  • a + 0.6a = 1600
  • 1.6a = 1600
  • a = 1600/1.6
  • a = 1000

<u>Find b:</u>

  • b = 0.6*1000 = 600

I need to find the area of below who can help please.
nasty-shy [4]

Triangle

Area = 1/2 b * h

Area = 1/2*15 * 9 = 1/2 * 135 = 67.5

Rectangle

Area = b * h

Area = 15 * 4

Area = 60

Trapezoid

Area = (1/2) * (b1 + b2)* h

Area = (1/2) * (15 + 18) * 4

Area = 1/2 * 33 * 4

Area = 66

Total Area

Total Area = 66 + 60 + 67.5 = 193.5 Answer
