Step-by-step explanation:

ΔQRS ~ ΔQRT

In similar triangles, corresponding angles are in same ratio.

$\frac{QS}{QR}=\frac{QR}{QT}\\\\\frac{25}{20}=\frac{20}{QT}$

Cross multiply,

QT * 25 = 20 * 20

$QT =\frac{20*20}{25}\\\\QT = 4*4\\\\QT = 16$

Answer:

$5\dfrac{1}{2}\ \text{kg}$

Step-by-step explanation:

Plant food used on strawberry plants is

$1\dfrac{2}{3}\ \text{kg}=\dfrac{5}{3}\ \text{kg}$

Plant food used on tomato plants is

$\dfrac{1}{4}\ \text{kg}$

Feeding the strawberry plants two times means

$\dfrac{5}{3}+2\times\dfrac{5}{3}=\dfrac{5}{3}+\dfrac{10}{3}\\ =\dfrac{15}{3}=5\ \text{kg}$

Feeding the tomato plants one more time means

$\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}\\ =\dfrac{1}{2}\ \text{kg}$

The plant food he will need is $5+\dfrac{1}{2}=5\dfrac{1}{2}\ \text{kg}$
