Answer:
A rectangular lot is 100 meters wide and 150 meters long.Give the length and width of another rectangular lot that has the same perimeter but a smaller area.
The rectangular lot is having length of 170 meters and width of 80 meters.
Step-by-step explanation:
Given:
A rectangle.
Length of the rectangle = 150 meters
Width of the rectangle =100 meters
So perimeter of this rectangle = 2 (width+ length)
And area of this rectangle =(width)(length)
- Perimeter =
=
= meters.
- Area =
=
= square meters.
Now we have to find an another rectangular lot which has the same perimeter but different area.
Note: Subtract 20 m from the width and add 20m length into the longer side. (We can try with another multiple of 10).
So,
The new width = 100-20 = 80 meters.
And the new length =150+20 = 170 meters.
Lets check the perimeter and its area.
The perimeter must be equivalent to 500 meters and its area be less than 30000 sq-meters.
- Perimeter =
=
= meters.
- Area =
=
= square meters.
Hence the rectangular lot with length 170 m and with 80 m proves to have same perimeter and smaller area.
(-9x -1) x (4x+1)
use foil method
-9x * 4x - 9x - 4x - 1
collect like terms by multiplying the -9x and the 4x together, then you add together both -9x and -4x. Then you have your answer below
-36x^2 - 13x - 1
2 boxes for $6.00 5 Bars each is 10 bars for $6.00 or $3.00 for 5 bars
so $6.00 divided by 10 =.60 or 60 cents per bar
12 bars for $7.44 is $7.44 divided by 12 =.62 or 62 cents per bar
so the difference between 60 cents and 62 cents is
2 cent Difference
