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

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

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

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

Find the value of 3 4(16 - 9). 31 49 58

maw [93]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$3+4(16-9)$

We first solve the brackets:

(16-9) = 7

Now, we multiply it with 4

$7\times 4=28$

Now, we add 3 to it:

$28+3=31$

Hence, the value of expression would be 31.

Therefore, First option is correct.

Find the solution of the system of equations 3x+4y=10 and x−y=1. Give the x value followed by the y value, separated by a comma.

Burka [1]

Answer:

x,y =2,1

Step-by-step explanation:

3x+4y=10 ................equ1

x-y=1 ................equ2

This system of equations forms a quadratic equation.

Lets use the substitution method in solving this set of equations

from equ 2; x=y+1

substitute x=y+1 into equ 1

3(y+1) +4y=10

3y+3+4y=10

7y=10-3

7y=7

y=7/7

y=1

but x=y+1

substitute the value of y into this equation to get x

x= 1+1

x=2

x,y=2,1
