Answer:

32  units^2

Step-by-step explanation:

To find the area of this irregular shape, you can split it into 3 triangles, and 1 square.

The formula for finding the area of a triangle is:

A = \frac{1}{2} bh

The formula for finding the area of a square is:

A = lw

<em><u>Finding area of large triangle:</u></em>

<em><u /></em>A = \frac{1}{2} (4)(10)\\\A = 20

<em><u>Finding area of bottom left triangle:</u></em>

<em><u /></em>A = \frac{1}{2} (2)(2)\\A=2

<em><u>Finding area of last triangle (bottom right):</u></em>

<em><u /></em>A = \frac{1}{2} (2)(6)\\A=6

<em><u>Finding area of square:</u></em>

<em><u /></em>A = (2)(2)\\A = 4

Answer:

32

Step-by-step explanation:

Area of a big right triangle = 1/2 * 4 * (2+2+6) = 1/2 * 4 *10 =20

Area of a left right triangle = 1/2* 2*2 = 2

Area of a right right triangle = 1/2 * 6*2 =6

Area of a square = 2*2 = 4

All together:

20+ 2+6+4 =32

Craig measured these three rectangles.​
WINSTONCH [101]

Answer:

Step-by-step explanation:

Perimeter of a rectangle is expressed as (2 length + 2 width) = 2(L + W)

A) The length of rectangle A is y + 1

The width of rectangle A is x

Perimeter of rectangle A = 2(y + 1 + x) = 2y + 2 + 2x

= 2x + 2y + 2

The length of rectangle B is 2x - 2y

The width of rectangle B is x + 1

Perimeter of rectangle B = 2(2x - 2y+ x + 1) = 4x - 4y + 2x + 2) = 4x + 2x - 4y + 2

= 6x - 4y + 2

The length of rectangle C is 3x + 3y

The width of rectangle C is 2x - 3

Perimeter of rectangle C = 2(3x + 3y + 2x - 3) = 6x + 6y + 4x - 6) =

(6x + 6y + 4x - 6)

= 10x + 6y - 6

B) The combined perimeters will be the sum if perimeter of rectangle A, perimeter of rectangle B and perimeter of rectangle C. It becomes

2x + 2y + 2 + 6x - 4y + 2 + 10x + 6y - 6

Collecting like terms

2x + 6x + 10x + 2y + 6y - 4y + 2 + 2 - 6

The combined perimeter = 18x + 4y - 2

Find the lateral area for the pyramid with the equilateral base.
Dafna11 [192]

Answer:

Option A is the correct answer.

Explanation:

 The given pyramid has 3 lateral triangular side as shown below.

 Base of triangle = 12 unit

 We need to find perpendicular.

  By Pythagoras theorem we have

            Perpendicular² = 10²-6²

           Perpendicular = 8 unit

So area of 1 lateral triangle = 1/2 x Base x Perpendicular.

                                             = 1/2 x 12 x 8 = 48 unit²

Area of lateral side = 3 x 48 = 144 unit²    

Option A is the correct answer.
