Question

question 11, rewrite the formulaThe area of a triangle is A-a. Rewrite the formula for b.b. Rewrite the formula for h.

Answer 1

Given the formula:

`A\text{ = }(1)/(2)bh`

a) Rewrite for b:

First step: Multiply 2 to both sides

`\begin{gathered} 2A\text{ = }(1)/(2)bh\text{ }\ast2 \\ \\ 2A\text{ = bh} \end{gathered}`

Second step: divide both sides by h

`(2A)/(h)\text{ = b}`
`\begin{gathered} \text{Thus,} \\ b\text{ = }(2A)/(h) \end{gathered}`

B) Rewrite for h:

First step: Multiply 2 to both sides

`\begin{gathered} 2A\text{ = }(1)/(2)bh\ast2 \\ \\ 2A\text{ = bh} \end{gathered}`

Second step: divide both sides by b

`\begin{gathered} (2A)/(b)\text{ = }(bh)/(b) \\ \\ (2A)/(b)\text{ = h} \end{gathered}`
`h\text{ = }(2A)/(b)`
