Answer:

The recommended number of flowers is 32

Step-by-step explanation:

Given

The attached graph

Required

The number of flowers when area = 15

First, calculate the slope (m)

Considering

$(x_1,y1) = (12,60)$

$(x_2,y_2) = (15,20)$

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{20-16}{15-12}$

$m = \frac{4}{3}$

Considering:

$(x_1,y_1) = (15,20)$

$(x_2,y_2) = (24,y)$

The slope is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{y - 20}{24 - 15}$

$m = \frac{y - 20}{9}$

Recall that: $m = \frac{4}{3}$

So:

$\frac{4}{3} = \frac{y - 20}{9}$

Multiply through by 9

$3*4 = y - 20$

$y = 20 + 3 * 4$

$y = 32$

$\text{Let the side of square 1, square 2 and square 3 be x, y and z respectively.}\\\\\text{Given that,}\\\\\text{Perimeter of square 1,~~ p =100 units.}\\\\\text{So}~ x=\dfrac p 4 = \dfrac{100}4 =25~\text{units.}\\\\\\\text{Area of square 2, a = 225 units}^2\\\\\text{So}~y = \sqrt{a} = \sqrt {225} = 15~ \text{units.}\\\\\text{Use Pythagorean theorem to find z}^2\\\\x^2 =y^2 +z^2 \\\\\implies 25^2 = 15^2 +z^2\\\\\implies z^2 = 625 - 225 = 400\\\\\\$

$\text{Hence the area of square 3 is 400 units}^2.$
