Question
Question:
Solve each equation for the indicated variable. Part a: P equals 2l plus 2w, solve for w. Part b: A equals one-half times b times h, solve for b. Part c: V equals l times w times h, solve for l. Part d: C equals 2 pi r, solve for r.
Rewriting Literal Equations | Solving for a Variable
This lesson covers how to rearrange common geometric formulas — perimeter, area, volume, and circumference — to isolate a specified variable. Students apply inverse operations (addition/subtraction and multiplication/division) to literal equations containing multiple variables, treating all non-target variables as constants.
In this lesson, you will learn to:
• Identify the target variable in a literal equation and apply inverse operations to isolate it
• Rearrange multi-step literal equations involving addition, subtraction, multiplication, and fractions
• Solve four standard geometric formula
