Answer:

c. 10 cm

Step-by-step explanation:

The parallel sides of trapizium are the bases so

base 1(B1) =9cm , base(B2)= 12cm

$area(a) = 105 {cm}^{2}$

the perpendicular distance means the height so lets find the height

area of trapizium= B1 + B2 × h

2

${105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h$

${105cm}^{2} = \frac{21cm}{2} \times h$

now we crisscross

${105cm}^{2} \times 2 = 21cm \times h$

${210cm}^{2} = 21cm \times h$

$\frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h$

h = 10 cm

Number 25 someone help me

Fittoniya [83]

The area of a triangle is given by the formula $A= \frac{1}{2}Bh$ , where B is the base and h is the height. We can rearrange this formula to solve for B.

$\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B$ .

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

$B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm$ .

40 mm is our final answer.
