A scale model of a street sign is in the shape of a triangle. The base is 4.25 cm and the height is 8.8 cm what is the area of t
agasfer [191]

Answer:

18.7 cm²

Step-by-step explanation:

To work out the area of a triangle you have to use the formula

\frac{1}{2} * B * H

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 4\frac{1}{4}

The height is 8.8 cm which will turn into 8\frac{8}{10}

Now we use the formula

 \frac{1}{2} * B * H

 \frac{1}{2} * 4\frac{1}{4} *8\frac{8}{10}

→ Convert to improper fractions

 \frac{1}{2} * \frac{17}{4} *\frac{88}{10}

→ Simplify

 \frac{187}{10}

→ Convert into decimal

18.7

Find the perimeter of the triangle. Round to the nearest tenth.
serious [3.7K]

Answer:

B)   17.1

Step-by-step explanation:

g = 5

f = 5

That means we have a 45-45-90 triangle

and the hypotenuse = \sqrt{2} times the length of a leg

Therefore, h = 5\sqrt{2} = 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?
