Question

unit 1c: solve literal equations & appli
attempting:
activity:
what is a formula, and give an example?
answer the following questions using the
formulas provided.
formula: ( p = 2 l + 2 w )
what is the perimeter of the rectangle?
the car is driven at 40 mph for 5 hours.
formula: ( d = r t )
how far does the car travel?

Explanation:

Step1: Calculate the perimeter of the rectangle

Given \( l = 20 \), \( w = 6 \), and the formula \( P=2l + 2w \).
Substitute the values: \( P = 2\times20+2\times6 \).
First, calculate \( 2\times20 = 40 \) and \( 2\times6=12 \).
Then \( P=40 + 12 \).

Step2: Calculate the distance traveled by the car

Given \( r = 40 \) (speed) and \( t = 5 \) (time), and the formula \( d=rt \).
Substitute the values: \( d=40\times5 \).

Answer:

The perimeter of the rectangle is \( 52 \). The car travels \( 200 \) miles.
