All the dimensions of a triangle were multiplied by the same factor. If the base of the triangle went from 1 centimeter to 3 cen
timama [110]
The answer is 9.

To calculate this, we will use Galileo's square cube law, used to describe the change of the area or the volume of the shape, when their dimensions increase or decrease. The formula used for change of the area is
A_2= A_1 (\frac{l_2}{l_1} )^{2}
A₂ - the area after the change,
A₁ - the area before the change,
l₂ - the dimension after the change,
l₁ - the dimension before the change.


It is given:
l₁ = 1 cm
l₂ = 3 cm

Let's use this formula for the mentioned triangle:
A_2=A_1( \frac{l_2}{l_1}) ^{2}  =A_1( \frac{3}{1})^{2} =A_1*3 ^{2} =9A_1

Therefore, the area of the triangle was multiplied by 9.

kipiarov [429]

Answer:

15.59 feet

Step-by-step explanation:

We need to find BC and CD

First find BC

We can use the Pythagorean theorem

AB^2 + BC^2 = AC^2

11^2 + BC^2 = 13^2

121 + BC^2 =169

Subtract 121 from each side

121-121+BC^2 = 169-121

BC^2 = 48

Take the square of each side

sqrt(BC^2 ) = sqrt( 48)

BC = 6.92820323

then we need to find CD

We can use the Pythagorean theorem

CD^2 + DE^2 = CE^2

CD^2 + 5^2 = 10^2

CD^2 + 25 =100

Subtract 25 from each side

CD^2 + 25-25 =100-25

CD^2 = 75

Take the square of each side

sqrt(CD^2 ) = sqrt( 75)

BC = 8.660254038


BD = BC +CD

     = 6.92820323 + 8.660254038

     15.58845727

Hep me on this please
Alona [7]

Answer:

The answer is 2240m².

Step-by-step explanation:

Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is height :

area =  \frac{1}{2}  \times (a + b) \times h

let \: a = 50 \\ let \: b = 90 \\ let \: h = 32

area =  \frac{1}{2}  \times (50 + 90) \times 32

area =  \frac{1}{2}  \times 140 \times 32

area = 70 \times 32

area = 2240 \:  {m}^{2}
