First cut the shape into a square, triangle and rectangle. Then add all 3 areas. Area of a quadrilateral is A= b x h So once square is 4 X 4= 16. The rectangle has a area of 4 x 2= 8. The triangle, using the formula 1/2bh has an area of 1/2 x 2 x 4 = 4. So the area of the shape is 16 + 8 + 4 = 28 units

Answer:

(a) 23, 35, 28, 33, 5, 12, 40, 25, 20, 18, 1, 16

1, 5, 12, 16, 18, 20 23, 25, 28, 33, 35, 40

n = 12 M = (20 + 23)/ 2 = 21.5

Q1 = (12 + 16) / 2 = 14 Q3 = (28 + 33) /2 = 30.5

(b) 22, 33, 25, 28, 5, 12, 35, 23, 20, 18, 1, 40, 16

1, 5, 12, 16, 18, 20 | 22 | 23, 25, 28, 33, 35, 40

n = 13 M = 22 Q1 = 14 Q3 = 30.5

(c) 20, 28, 23, 25, 3, 5, 33, 22, 18, 16, 40, 1, 35, 12

1, 3, 5, 12, 16, 18, 20, 22, 23, 25, 28, 33, 35, 40

n = 14 M = (20 + 22)/2 = 21 Q1 = 12 Q3 = 28

(d) 20, 28, 23, 25, 3, 5, 30, 22, 18, 40, 16, 35, 1, 33, 12

1, 3, 5, 12, 16, 18, 20 | 22 | 23, 25, 28, 30, 33, 35, 40

n = 15 M = 22 Q1 = 12 Q3 = 30

A father's age is 4 times as that of his son's age. in 5 years time, the father will be 3 times as old as his son. what are thei

Vadim26 [7]

Answer:

<h3>present age of son = 10 </h3><h3>present age of father = 40</h3>

Step-by-step explanation:

Let, present age of son be 'x'

present age of father be 'y'

y = 4x→ equation ( i )

After five years,

Son's age = x + 5

father's age = y + 5

According to Question,

$y + 5 = 3(x + 5)$

Put the value of y from equation ( i )

$4x + 5 = 3(x + 5)$

Distribute 3 through the parentheses

$4x + 5 = 3x + 15$

Move variable to L.H.S and change it's sign

Similarly, Move constant to R.H.S. and change its sign

$4x - 3x = 15 - 5$

Collect like terms

$x = 15 - 5$

Calculate the difference

$x = 10$

Now, put the value of X in equation ( i ) in order to find the present age of father

$y = 4x$

plug the value of X

$= 4 \times 10$

Calculate the product

$= 40$

Therefore,

Present age of son = 10

present age of father = 40

Hope this helps..

Best regards!!
