Answer:

A = s²

Step-by-step explanation:

A = s² where s represents the side lengths

Since the side lengths of a square are always the same, you can use the formula A = s² for a square instead of using A=l(w)

Item 12

Answer:

The height is 4.472

Step-by-step explanation:

That formula is Heron's formula.

Where "s" is calculated like this:

s = (a + b + c) / 2

In this case:

a = 14

b = 12

c = 6

replacing:

s = (14 + 12 + 6) / 2

s = 16

Now we calculate the area:

A ^ 2 = 16 * (16−14) * (16−12) * (16−6)

A ^ 2 = 1280

A = 35.777

The area of the triangle is:

A = b * h / 2

In this case we will take the base as the longest side of the triangle, that is to say = 14

Thus:

h = A * 2 / b

h = 35.777 * 2/16

h = 4.472

So the height is 4.472

Hhelp me pleaseeeeee

svetlana [45]

A. Area = ½b × h

= ½ × 16 × 9

= 72

B. Area = b × h

= 26 × 18

= 468

C. Area = a²

= 11²

= 121

D. Area = ½(a+b) × h

= ½(6+21) × 8

= 108

Hope this helps :)

Answer:

The equation of the circle having centre (-5,-9) and radius r=3 is

x² + 10 x +y² + 14 y + 65 = 0

Step-by-step explanation:

<u>Explanation</u>:-

From graph The centre of the circle C( -5 , -7)

The radius of the circle r = 3cm from the centre of the given circle

The equation of the circle

From graph the centre ( h, k) = ( -5,-7) and r = 3cm

$(x-(-5))^2+(y-(-7))^2 = 3^2$

x² + 10 x +25 +y² + 14 y + 49 =9

x² + 10 x +25 +y² + 14 y + 49 -9=0

The equation of the circle

x² + 10 x +y² + 14 y + 65 = 0
