Tanya runs diagonally across a rectangular field that has a length of 40 yards and a width of 30 yards. How far did Tanya run?

Yuliya22 [10]

Tanya run 50 yards across the diagonal of the rectangular field.

<u>Step-by-step explanation</u>:

Step 1 :

Length of the rectangular field = 40 yards
width of the rectangular field = 30 yards

Step 2 :

Measure of the diagonal = √(length^2 + width^2 )

Step 3 :

Diagonal = √(40^2 + 30^2 )

= √(1600 + 900)

= √2500

= ±50

Step 4 :

Since distance cannot be negative, The measure of diagonal = 50 yards.

∴ Tanya runs diagonally across a rectangular field is 50 yards.

Avery planned a circular garden and path as shown below. The radius of the garden is 4 feet and the path around the garden is 2

Digiron [165]

Answer:

Option C) 113.0 feet squared

Step-by-step explanation:

We are given the following in the question:

Radius of circular garden = 4 feet

Length of path around garden = 2 feet

We have to find the total area of garden and path.

The garden and path together makes a bigger circle with radius

$R = 4 + 2 = 6\text{ Feet}$

Area of garden and path =

$A = \pi R^2$

Putting values, we get,

$A = 3.14\times (6)^2 = 113.04\\A \approx = 113.0\text{ square feet}$

Thus, the correct answer is

Option C) 113.0 feet squared
