Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = A=\frac{a+b}{2} h

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738

Hence the answer is 738

The length of the midsegment of a triangle is always half the length of the side it is parallel to true or false
Vladimir [108]
True. The midsegment of a triangle is halfway up the triangle, and since the top half and the full triangle are similar triangles, its dimensions are proportional.

This means half the height will give half the base (midsegment). So the midsegment is always half the length of the side it's parallel to.
