<u>Finding area of triangle</u> --> \frac{1}{2}*b*h

  • b --> length of base of triangle
  • h --> length of height of triangle

     Question 1:

         a.   Area = \frac{1}{2}*b*h = \frac{1}{2}*20*21 = 210 m^2

         b. Area = \frac{1}{2}*b*h = \frac{1}{2}*4*7 = 14 ft^2

         c. Area = \frac{1}{2}*b*h= \frac{1}{2}  *21*19=199.5in^2

     Question 2:

         a. Area = \frac{1}{2}*b*h = \frac{1}{2} *36*15 = 270cm^2

         b. Area = \frac{1}{2}*b*h = \frac{1}{2} *18*18 = 162m^2

         b. Area = \frac{1}{2}*b*h = \frac{1}{2} *17*32 = 272cm^2

     Question 3:

         a. Area = \frac{1}{2}*b*h = \frac{1}{2} *24*29 = 348ft^2

         b. Area = \frac{1}{2}*b*h = \frac{1}{2} *20*23 = 230in^2

         c. Area = \frac{1}{2}*b*h = \frac{1}{2} *25*25 = 312.5cm^2

<u>Finding Area of Parallelogram</u> --> b * h

  • b: length of base of parallelogram
  • h: length of height of parallelogram

     Question 1

         a. Area = b * h = 24 * 26 = 624cm^2

         b. Area = b * h = 15 * 30 = 450in^2

         c. Area = b * h = 21 * 31 = 651 mm^2

 

      Question 2

         a. Area = b * h = 18 * 17 = 306 in^2

         b. Area = b * h = 10.5 * 15 = 157.5m^2

         c. Area = b * h = 12.5*11=137.5cm^2

 

      Question 3:

          a. Area = b * h = 5.7*11.5=65.55in^2

          b. Area = b * h = 8 * 12.5 = 100ft^2

          c. Area = b * h = 1.7 * 3.6 = 6.12m^2

Hope that helps!

Answer:

1a. 210 m^2  1b. 14 ft^2  1c. 199.5 in^2

2a. 270 cm^2  2b. 162 m^2  2c. 272 cm^2

3a. 348 ft^2  3b. 230 in^2  3c. 312.5

Step-by-step explanation:

The area of a triangle can be calculated with one equation...

A = 1/2bh

b stands for base, h stands for height

1a. A = 1/2(21)(20)

    One half divides 20 easily..

A = 21(10)

A = 210

1b. A = 1/2(7)(4)

    One half divides 4 easily..

A = 2(7)

A = 14

1c. A = 1/2(19)(21)

A = 1/2(399)

A = 199.5

2a. A = 1/2(36)(15)

    One half divides 36 easily..

A = 18(15)

A = 270

2b. A = 1/2(18)(18)

   One half divides 9 easily..

A = 9(18)

A = 162

2c. A = 1/2(32)(17)

  One half divides 32 easily..

A = 16(17)

A = 272

3a. A = 1/2(29)(24)

  One half divides 24 easily..

A = 12(29)

A = 348

3b. A = 1/2(23)(20)

  One half divides 20 easily..

A = 10(23)

A = 230

3c. A = 1/2(25)(25)

A = 1/2(625)

A = 312.5

( 32.45 - 4.8) - 2.06
Igoryamba

Answer:

25.59

Step-by-step explanation:

The first thing that you will do is solve parenthesis (remember PEMDAS).

(32.45-4.8) - 2.06

(27.65) - 2.06

Then do the subtraction.

(27.65) - 2.06=

25.59

A line with a slope of -1 passes through the point (0,0). What is its equation in slope-intercept form?​ Please answer quickly.
rusak2 [61]

Answer:

y = -x

Step-by-step explanation:

The line has a slope of -1 and it passes through point (0,0)

Taking another point (x,y) on the line;

Slope = change in y ÷ change in x

For our case; slope = \frac{y - 0}{x - 0} = -1

Cross multiplying this gives;

y = -x
