Question

Emily is mowing her lawn which is in the shape of a rectangle with a length of 10 feet and width of 12 feet. Emily completed mowing it in 3 hours. What is the unit rate at which Emily mowed her lawn?

Answer 1

So what you do first is find the area of this lawn and you do 10 by 12 and multiply those and you get 120 feet so now what you do is divived 120 by 3 and you get 40 so that means she mowed 40 ft in each hour so that would be the unit rate.

Answer 2

Step by step explanation:

Given that,

The shape of the lawn is rectangular

Length of the lawn = 10 feet

Width of the lawn = 12 feet

Time to complete mowing = 3 hours

Rate = ?  

Step 1: find the area of the lawn

Area of rectangle is  

A = l * w

10* 12 = 120 Feet

Area / no of hours for the mowing to complete  

120/3 = 40

This meant that the rate at which Emily mowed her lawn is 40 ft per hour
