Answer:

13 sq cm.

Step-by-step explanation:

To find the area of this irregular figure, we will need to find the areas of a rectangle and triangle within this figure.

To find the area of the rectangle, we can simply do:

1 × 4= 4  sq cm.

Now, this is where it gets a little trickier. To find the area of the triangle, we will first need to determine the base and height.

We can see from the diagram that to find the base, we need to subtract:

7-4= 3 cm. This is the base of ONLY the triangle.

To find the height, we will need to do:

5+1= 6 cm. This is the total height of the entirety of the triangle.

We can now use the Triangle Area formula: \frac{1}{2}(bh), to calculate the area of the triangle.

\frac{1}{2} (6*3)= 9 sq cm.

Finally, add the areas of the rectangle and triangle together, giving you:

9+4= 13 sq cm.

Step-by-step explanation:

<u>Area of circle:</u>

  • A = πr²

<u>Circumference of circle:</u>

  • C = 2πr

<u>Given</u>

  • C = 55 m

<u>Find r using the second formula:</u>

  • 2πr = 55
  • 2*3.14r = 55
  • r = 55/6.28
  • r = 8.8 (rounded)

<u>Find area using the first formula:</u>

  • A = 3.14*8.8²
  • A = 243 m² (rounded)

Macy's if offering a sale where you can use two different coupons, Coupon A gives 15%
Juliette [100K]

The ticket price of the item after applying coupon B first and then coupon A is $65.45

Coupons reduce the ticket price of an item.

<u><em>Ticket price</em></u><u><em> after </em></u><u><em>coupon B i</em></u><u><em>s applied </em></u>

An item costs $80. After applying the coupon B which gives, $3 off the price, the cost of the item reduces to $77 ($80 - $3).

The ticket price of the item after coupon B is applied is $77

<em><u>Ticket price </u></em><em><u>after c</u></em><em><u>oupon A </u></em><em><u>is applied </u></em>

The item costs $77 when coupon B is applied. If the discount is 15% off on coupon A, it means that the item costs 85%( 100 - 15%) of its initial price.

Ticket Price of the item = percentage price x price of the item after the first coupon B was applied

85% x $77

0.85 x $77 = $65.45
