Answer 1

Answer:

Step-by-step explanation:

b = sqrt(2 * L)                 Given

L = 4.5                            Given

b = sqrt(2 * 4.5)

b = sqrt(9)

b = 3

Answer 2

Answer:

b = 9

Step-by-step explanation:

Given :-

$\small \sf \: b = \sqrt{2 \it \: l}$

$\small \: l = 4.5$

Solution :-

$\small \sf \: b = \sqrt{2 \it \: l}$

plug the values of l in the equation

$\small \sf \leadsto \: b = \sqrt{2 × 4.5}$

$\small \sf \leadsto \: b = \sqrt{9}$

$\small \sf \leadsto \: b = 9$
