Answer:

128 ft^2 needed

Step-by-step explanation:

Given

See attachment for missing details

Required

Determine the number square feet needed

First, calculate the inner area (A1)

A_1 = Length * Width

A_1 = 20ft * 8ft

A_1 = 160ft^2

Next, calculate the outer area (A2)

A_2 = Length * Width

A_2 = 24ft * 12ft

A_2 = 288ft^2

The area of the planter is:

Area = 288ft^2-160ft^2

Area = 128ft^2

Hence, he needs 128 square feet

I need help with equivalent ratios
natima [27]
An equivalent ratio is the same as an equivalent fraction. So if you need an equivalent ratio for 2/3 you have to multiply each number by the number you are multiplying by!

What is the slope of the line?<br><br>1<br>1/2<br>-2<br>2​
Ray Of Light [21]

Answer:

2

Step-by-step explanation:

The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.
