You are Looking at two area rugs for your bedroom. One is a square with a side length of 6.3 feet the other is rectangle that is

Ray Of Light [21]

Answer:

Part a) The square rug cover the greater area

Part b) The square rug cover 0.33 square feet more than the rectangular rug

Step-by-step explanation:

step 1

Find the area of the square rug

The area of a square is

$A=b^2$

where

b is the length of the square

we have

$b=6.3\ ft$

substitute

$A=(6.3)^2=39.69\ ft^2$

step 2

Find the area of the rectangular rug

The area of the rectangle is

$A=LW$

we have

$L=4.8\ ft\\W=8.2\ ft$

substitute

$A=4.8(8.2)=39.36\ ft^2$

step 3

Compare the areas

$39.69 > 39.36$

The square rug cover the greater area

step 4

Find the difference

$39.69-39.36=0.33\ ft^2$

The square rug cover 0.33 square feet more than the rectangular rug

Q3. a cyclist bikes x distance at 10 miles per hour and returns over the same path at 8 miles per hour. what is the cyclist's av

Sladkaya [172]

If he bikes for 10 miles per hour and 8 miles per hour for the same distance x miles, he went 10 miles per hour for x/10 hours, as Distance = Rate*Time and on the way back he would go for x/8 hours. So then he went 2x distance, in x/8 + x/10 hours. Since x/8 + x/10 = 10x/80 + 8x/80 = 18x/80 = 9x/40, he went 2x miles in 9x/40 hours. this can be converted into a rate with the above equation Distance = Rate*Time, so 2x=(9x/40) * Rate, thus we divide by 9x/40 on both sides to get 80x/9x = Rate, the x cancels out, and we get 80/9 Miles per hour.

A rectangle has an area of 228 ft and a length that measures 12ft find the perimeter

Blizzard [7]

The area of a rectangle is the width times the length:

$A = w\cdot l \iff 228 = w\cdot 12 \iff w = \dfrac{228}{12} = 19$
