answer:

157 inches²

step-by-step explanation:

  • we have to break this down into parts and find the area of each part and then add them up so we have the area for the whole thing

rectangle:

5 X 14 = 70 inches²

big semicircle:

  • solve this like a simple circle and then divide by 2 since this is half

area = πr²

  • insert what we know from the question

area = (3.14)(7)²

  • the radius would be seven because as you can see the length of a side of the rectangle is 14 and this is also the diameter of the circle since they are attached and share it
  • the radius is half of the diameter so we get 7

area = 3.14(49)

        = 153.86 inches²

  • now divide this by 2 since it is semicircle

153.86 / 2 = 76.93 inches²

small semicircle:

area = (3.14)(2.5)²

  • i followed the same method as last, except the numbers are different

area = 3.14(6.25)

        = 19.625 inches²

  • now divide by 2

19.625 / 2 = 9.8125 inches²

  • finally, add up all the separate areas you got

70 inches² + 76.93 inches² + 9.8125 inches²

= 156.7425 inches²

= 157 inches²

Answer:

  • 157 in²

Step-by-step explanation:

The area of the shape is the sum of three sections

<u>1. Rectangle</u>

  • A = 5*14 = 70 in²

<u>2. Bigger semicircle</u>

  • A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)

<u>3. Smaller semicircle</u>

  • A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)

<u>Total area:</u>

  • 70 + 77 + 10 = 157 in²

Answer:

2

Step-by-step explanation:

We can set up equation for this one.

Let's say the number is X.

the sum of X and 14 can be expressed as : X+14

five times the sum of X and 14 can be expressed as 5(x+14)

and 5(X+14) = 80

5(x+14) = 80\\x+14 = 80 \div 5 = 16\\x = 16-14 = 2

The number  is 2
