a square red rug has a purple square in the center. the side length of the purple square is x inches. the width of the red band

Bumek [7]

Answer:

Area of red band is $(20x + 100) inch^{2}$

Step-by-step explanation:

We know that area of square = $side^{2}$

Please refer to the attached figure, we have to calculate the area of red band.

Required area = Area of square ABCD - Area of purple square

Side of purple square = $x$

So, area of purple square = $x^{2}$

ABCD is a square with purple square at the center and there is symmetry in the figure.

So, width of red band towards both the end is 5 inches.

$\Rightarrow \text{side of }ABCD = 5 + 5 +x = (x+10) inches$

Required area = $(x+10)^{2} - x^{2}$

Using formula $a^{2} - b^{2} = (a-b)\times (a+b)$

$\Rightarrow (x+10-x)(x+10+x)\\\Rightarrow (10)(2x+10)\\\Rightarrow (20x+100)$

Hence, Area of red band is $(20x + 100) inch^{2}$

Jobisdone [24]

If it the orginial price of the sweater is 75%, then 25% was taken off.

Turn 25% into a decimal.

.25

Multiply that by 27.

27*.25= 6.75

Add that to the discounted price.

27+6.75= 33.75

33.75 is your answer.

I hope this helped you.

The area of a rectangular playground enclosure at francis lewis hw is 500 square meters. the lenght of the playground is 5 meter

Alex Ar [27]

A=L*W
L=W+5
A=(W+5)W
500=W²+5W
W²+5W-500=0

W=(-5+/-√(25+4*500))/2=(-5+/-√2025)/2=(-5+/-45)/2
we are going to take only positive value, so W=(-5+45)/2=20
L=W+5=20+5=25
W=20,
L=25
