What is the surface area of the figure?

Answers

9514 1404 393

Answer:

  B.  24 cm²

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

Here, you have a base of 4 cm and a height of 3 cm, so the area is ...

  A = (1/2)(4 cm)(3 cm) = 6 cm²

__

The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...

  A = WH

  A = (4 cm)(4.5 cm) = 18 cm²

The total area is the sum of the areas of the parts:

  total area = triangle area + rectangle area

  total area = 6 cm² + 18 cm² = 24 cm²

Answers

Answer:

86: The basketball team scored 86 points

50: You deposited $50 in your bank account

8: A dolphin jumped 8 feet out of the water

-86: The elevation of Death Valley is 86 meters below sea level

-50: Eva withdrew $50 out of her account

-8: The temperature dropped 8 degrees

Step-by-step explanation:

In the bank situation you are losing or gaining something for example Eva withdrew $50 out of her account, since her bank account has less money in it its negative 50 and vice versa with depositing 50 in the bank account (adding more money to account makes it positive 50)
