Answer:
18.7 cm²
Step-by-step explanation:
To work out the area of a triangle you have to use the formula
Where "B" is the base and "H" is the height
Since these are decimals, I like to convert them into fractions which makes them easier to calculate with
The base is 4.25 cm which will turn into
The height is 8.8 cm which will turn into
Now we use the formula
→ Convert to improper fractions
→ Simplify
→ Convert into decimal
18.7
Answer:
B) 17.1
Step-by-step explanation:
g = 5
f = 5
That means we have a 45-45-90 triangle
and the hypotenuse = times the length of a leg
Therefore, h = 5 = 7.1
5 + 5 + 7.1 = 17.1
Note: If you have not been taught about 45-45-90 triangles, then use the Phythagorean theorem. OK?
