What is the area of this ^2
Ad libitum [116K]
<h2>Question:- Area of the given diagram</h2>

<h2>Answer :- </h2>

Divide the diagram as shown in attachment.

Now first calculate the area of the rectangle having side 1 and 12

So area = length ×breadth

Area = 1× 12 = 12 unit²

Now find the Area of the remaining triangle with sides 12,13,5 units

So

Area =  \frac{1}{2}  \times base  \times height \:

Now put the value as -> base= 5 and height= 12

Area =  \frac{1}{2}  \times base  \times height \:  \\ Area =  \frac{1}{2}  \times 5 \times 12 \\ Area =  \frac{1}{ \cancel2}  \times 5 \times  \cancel{12}^{ \:  \: 6}  \\ Area = 5 \times 6 \\ Area = 30 \: units^{2}

Now add both areas for your answer

Area{ \tiny{1}} = 12 {units}^{2}  \\ Area{ \tiny2} = 30 {units}^{2}  \\ Area{ \tiny{total}} = Area{ \tiny{1}} + Area{ \tiny{2}} \\ Area{ \tiny{total}} = 12 + 30 = 42 {units}^{2}

Which expression is equivalent to 5(4x+3) - 2x
Troyanec [42]

Good evening  

Answer:

  1. 18x + 15
  2. 3(6x + 5)

Step-by-step explanation:

Unfortunately you didn’t provide the expressions to chose from ,however we can get other expressions From this one like this:

5(4x+3) - 2x = 20x + 15 - 2x

                   = (20x - 2x) + 15

                   = 18x + 15

we can also write 18x + 15 = 3×(6x) + 3×(5x) = 3(6x + 5)

then

these two expressions :

  • 18x + 15
  • 3(6x + 5)

are equivalent to 5(4x+3) - 2x
