1 2/5 - (-3/5)

First, we're going to convert 1 2/5 into an improper fraction.

1 2/5 = 7/5

7/5 - (-3/5)

Subtracting a negative is the same as adding, so the problem will look like:

7/5 + 3/5

The denominators are the same, so we just add the numerators.

The answer is 10/5, or 2.

The area of a rectangular park is same as area of a square park. If the length
Leona [35]

Answer:

<h2> 8m</h2>

Step-by-step explanation:

Step one:

given data

length of rectangle= 24.5m

let the width be x

width of square= 14m

let the length be x

Step two:

we know that the area of a rectangle is

Ar= Length * width

Ar=24.5*x-----------1

Also, the area of the square is

As= Length * width

for square L=W

As= 14*14-----------------2

As=196m^2

equating 1 and 2 we have

14*14=24.5x

196=24.5x

divide both sides by 24.5

x=196/24.5

x=8m

<u>The Breadth/width of the rectangular park is 8m</u>

Step-by-step explanation:

The first quartile can best described as  the median of the lower half of a data set ordered from least to greatest.
