Answer:

<h2>2nd Option:</h2><h2> $6 {x}^{2} + 43x + 55$ </h2>

Step-by-step explanation:

Given, 

Dimensions of the rectangular garden = 2x+11, 3x + 5

Therefore ,

Area of the rectangular garden

= (2x+11) × (3x + 5)

= 3x(2x + 11) + 5(2x + 11)

$= {6x}^{2} + 33x + 10x + 55$

$= 6 {x}^{2} + 43x + 55(ans)$

2(vh)/k=r Solve equation for v in terms of all other variables involved

aivan3 [116]

The equation v in terms of other variables is v = kr/2h

<h3>What is the subject of an equation?</h3>

It is a variable which is expressed in terms of other variables involved in the formula.

Formulas are written so that a single variable, the subject of the formula is on the L.H.S. of the equation. Everything else goes on the right side of the equation. We evaluate the formula by substituting for the literal numbers on the right hand side.

2(vh) / k = r

by cross multiplication

2(vh) = kr

divide both sides by 2h

v = kr/2h

In conclusion, v in terms of other variables is kr/2h
