A rectangular lot is 80 yards wide and 115 yards long. Give the length and width of another rectangular lot that has the same perimeter but a smaller area.
p=195 i think
so perimeter for a rectangle = width + width + length + length
oh so 390
There you go! Now you need to come up with a width and a length that will give you a perimeter of 390
and note that the larger the difference between the width and length, the smaller the area
65 and 6?
doesn't add up to 390-
65 and 6 doesn't work out 65 + 65 + 6 + 6 = 142 not 390
oh
also remember what @snowflake0531 said we want it to also have a smaller area so first choose one side of your rectangle like if we make one side as 5, what would the other side be?
the oppisite side would be 5
the other length... (390 - 2(5))/2
190
and if your triangle has sides 190 and 5 what is the area? just multiply because area = length times width
we just have to make sure the area of this new rectangle is smaller than the area of the first rectangle that was 80 yards wide and 115 yards long
950
and what is the area of the original rectangle 80 * 115 =
9200 is 80 times 115
and so the area is smaller!
so that means you can have 190 and 5 as your answer
ok thx
