Question

Answer 1

99cm^2

Explanation:

hope this helps :)

Answer 2

Answer: 99 square cm

Work Shown

area = 0.5*base*height

area = 0.5*18*11

area = 99 square cm

Notes:

• You can use the fraction 1/2 in place of 0.5
• An alternative formula is area = (base*height)/2
• The side 14 cm is never used. Your teacher put that as a distraction.
• The base and height are always perpendicular. If the base isn't horizontal, then it helps to rotate the triangle until it is horizontal.
• The area units "square cm" can be abbreviated to "sq cm" or cm^2 or
  `\text{cm}^2`
