Question

answer the following questions using the formulas provided.
rectangle perimeter formula: ( p = 2l + 2w )
what is the perimeter of the rectangle?
the car is driven at 80mph for 3 hours.
formula: ( d = rt )
how far does the car travel?

Explanation:

Step1: Calculate the perimeter of the rectangle

Given the formula \( P = 2l+2w \), where \( l = 10 \) and \( w = 4 \).
Substitute the values into the formula: \( P=2\times10 + 2\times4 \).
First, calculate \( 2\times10=20 \) and \( 2\times4 = 8 \).
Then, add the results: \( P=20 + 8=28 \).

Step2: Calculate the distance the car travels

Given the formula \( d=rt \), where \( r = 80 \) (speed) and \( t = 3 \) (time).
Substitute the values into the formula: \( d=80\times3 \).
Calculate \( 80\times3=240 \).

Answer:

The perimeter of the rectangle is \( 28 \). The car travels \( 240 \) miles.
