Mia found the area of a polygon The area is 32 square cm.

solniwko [45]

Answer:

Only the isosceles trapezoid has an area of 32 cm².

Step-by-step explanation:

Let's calculate the area of each polygon.

For the two triangles we have:

$A_{t} = \frac{bh}{2} = \frac{2 cm*4 cm}{2} = 4 cm^{2}$

This polygon does not have an area of 32 cm².

For the rectangle we have:

$A_{r} = bh = 6 cm*4 cm = 24 cm^{2}$

This polygon does not have an area of 32 cm².

For the rectangle trapezoid we have:

$A_{rt} = A_{t} + A_{r} = (4 + 24) cm^{2} = 28 cm^{2}$

So, this polygon does not have an area of 32 cm².

Finally, for the isosceles trapezoid:

$A_{it} = A_{t}*2 + A_{r} = (4*2 + 24) cm^{2} = 32 cm^{2}$

This polygon does have an area of 32 cm².

Therefore, only the isosceles trapezoid has an area of 32 cm².

I hope it helps you!

Find the missing side of the right triangle

vlada-n [284]

Answer:

$a {}^{2} + b {}^{2} = c {}^{2} \\ b {}^{2} = \sqrt{c {}^{2} - a {}^{2} } \\ b = \sqrt{14 {}^{2} - 3 {}^{2} } \\ b = \sqrt{196 - 9} \\ b = \sqrt{187} \\ b = 13.7$

Kamil and Sean share some money in the ratio 3:5. Sean gets $56 more than Kamil. How much do they get each?

liq [111]

Let Kamil get x. Therefore Sean would get (x + 56).

Kamil and Sean are in the ratio: 3:5

That means: x : (x + 56) = 3 : 5

x / (x + 56) = 3/5

5*x = 3*(x + 56)

5x = 3*x + 3*56

5x = 3x + 168

5x - 3x = 168

2x = 168

x = 168 / 2

x = 84

Therefore Kamil had, x = 84, and Sean had (x + 56) = 84 + 56 = 140

Kamil had $84 and Sean had $140
