A rectangular field is 130 yards long and 90 yards wide. Give the length and width of another rectangular field that has the same perimeter but a smaller area.

i would abso. murder this, @snowflake0531

snowflake0531:

imagine murdering a question

HaydenwH:

i tend to majorly overthink things.

snowflake0531:

So we have 130 and 90 as the two side lengths which means we have 220 yards in all for length and width The area for 130 x 90 = 16200 So you want to use the 220 yards and make two lengths that multiply together to less than 16200 an example would be 1 x 119 which is 119 yards lol

so the 119 and 1 would be the new length and width?

snowflake0531:

THat's an example, you can use other side lengths too i mean i don't think you want a field with 1 yard as the width o-O

Gabby07:

ooo ok

Gabby07:

but i still dont get it ;-;

snowflake0531:

Well, you can do 1 x 119 2 x 118 3 x 117 and for example 15 x 105

Gabby07:

but the correct answer was 16 length 12 width, how do you get that answer?

snowflake0531:

that's wrong

snowflake0531:

That wouldn't be the same perimeter then

Gabby07:

when i typed the answer that you gave me it was incorrect

snowflake0531:

there is more than one answer, and 16 x 12 is definitely not one of them

Gabby07:

thats what the program says
