Answer:

a. b = 2A/a

b. 30

Step-by-step explanation:

a. to solve for b:

[tex]A = 1/2 ab[/tex]

multiply both sides by 2

[tex]2A = ab[/tex]

divide both sides by a

[tex]2A/a=b[/tex]

so b = 2A/a

b. using the equation b = 2A/a

[tex]b = 2*18/(6/5)\\= 36/(6/5)\\= 30[/tex]

Answer:

a) b = 2A/a
b) b = 30

Step-by-Step Solution:

a) Solve the following …

A = 1/2ab
A = a/2b
A * 2 = ab
2A = ab
2A/a = b
=> b = 2A/a

b) Evaluate b when A = 18 and …

=> b = 2A/a
=> A = 18
=> a = 6/5

Substitute the Values in the Equation :-

b = 2A/a
b = 2(18)/(6/5)
b = 36 ÷ 6/5
b = 36 * 5/6
b = 180/6
=> b = 30

Hence, b = 30 when A = 18 and a = 6/5
