Likurg_2 [28]3 years ago
4 0

Answer:  12 m²

Step-by-step explanation:

Find height first:

It would be a 3-4-5 triangle, (or you could use Pythagorean theorem) so the height would equal 4.

Equation:

\frac{1}{2}bh = \frac{1}{2}(6)(4) = 12 m²

Find the area of the hexagon.<br> A) 36 in2 <br> B) 52 in2 <br> C) 78 in2 <br> D) 144 in2
s2008m [1.1K]

Answer: C) 78 in2

Step-by-step explanation:

The polygon is divided into two trapezoids with equal measurements.

Area of a trapezoid:

1

2

(b1 + b2)h

Since the area of the hexagon equals the area of two trapezoids with equal measurements, do not multiply by 1/2.

(b1 + b2)h

(10 + 16)3

26(3)

78 in2

5.<br> A number is squared, then multiplied by 6. The result is 54. What was the number?<br> Answer:
madam [21]

Answer:

± 3

Step-by-step explanation:

let n be the number then the number squared is n² , so

6n² = 54 ( divide both sides by 6 )

n² = 9 ( take the square root of both sides )

n = ± \sqrt{9} = ± 3

That is the number is 3 or - 3
