I rectangular garden is fence on all sides with 245 feet of fencing for garden is 6 feet longer than it is wide find the length and the width and the garden

 1591

Step-by-step explanation: Let's look for the clues.  A rectangle has 4 sides, 2 sides are equal length and so are the other 2 sides of a rectangle.  

Perimeter of a rectangle is Side 1 + Side 2 + Side 3 + Side 4.

Side 1 and Side 3 (for example) are the longer sides of the rectangle, they will be equal.

Side 2 and 4 (for example) are the shorter sides of the rectangle, they will be equal.

Sides 1 + 2 + 3 + 4 = 160

Side 1 and Side 3 are equal to "x + 6", or in plain english 6 feet longer than the other sides.

Side 2 and 4 are equal to "x"

Adding them all together

x + x + x+6 + x+6 = 4x + 12 = 160

4x + 12 = 160 is now a much simpler algebra problem.

4x = 148

x = 37

So the shorter sides are each 37, the longer sides are each 43.

The area of a rectangle is length times width.

37 x 43 = 1591 ft squared

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
