There is one mother and a baby laying under the tree and enjoying the view. Near the pond a girl is pushing a boy into the pond and a boy is swimming in the pond. There are two boy playing football.

Step-by-step explanation:

Let the third proportion be x

Therefore third proportion of 4.5,6 will be given as

4.5:6::6:x

⇒

6

4.5

=

x

6

Cross multiply

⇒4.5×x=6×6

⇒4.5×x=36

⇒x=

4.5

36

On calculating

⇒x=8 answer

Answer:

Step-by-step explanation:

If a : b = c : d are in proportion then a/b = c/d

i.e. ad = bc

Product of extremes = Product of means

This is called cross product rule

Let the third proportion be 'x'

⇒ 4  : 5 : x : 6

⇒ 5x = 24

⇒ x = 24/5

Answer:

56.25%

Step-by-step explanation:

let the length and breadth of rectangle be x and y respectively

so initially, area = xy

by increasing both by a quarter, the area will be,

(x + x/4)(y+ y/4)

= (4x+x/4)(4y+y/4)

= (5x/4)(5y/4)

= 25xy/16

Hence the new area is 25/16 times of xy i.e. older area

Percentage= 25xy/16 × 100 × 1/xy

= 2500/16= 156.25%

So rise in area will be 156.25-100 = 56.25%

Answer: Area will increase 56.25%.

Given: Each side is increased by a quarter.

To Find: The percentage increase in the area of a rectangle.

Step-by-step explanation:

Step 1: A rectangle is a two-dimensional (2D) form in which the four angles are all right angles and the opposite sides are parallel and equal to one another.

A rectangle's area (A) is calculated by multiplying its length ('x') by its breadth ('y'). Area of Rectangle is therefore equal to (xy) square units.

Step 2: Let the length of rectangle is x and breadth is y.

So, area of the rectangle = xy

If each side is increased by a quarter then new length of the sides are length will be [tex]x+\frac{x}{4} =\frac{5x}{4}[/tex] and width will be [tex]x+\frac{y}{4} =\frac{5y}{4}[/tex].

Now, new area of rectangle =

[tex]=\frac{5x}{4} \times \frac{5y}{4} \\\\=\frac{25}{16} xy\\\\=(1+\frac{9}{16})xy[/tex]

Step 3: Now percentage change = ((new area - area) ÷ area) x 100

[tex]= \frac{(1+\frac{9}{16})xy-xy}{xy} \times 100\\\\= \frac{(\frac{9}{16}xy)}{xy} \times 100\\\\=\frac{9}{16} \times 100\\\\=56.25[/tex]

Hence we can say that after increased by a quarter of the sides of a rectangle the area will increase 56.25%.
