Question

The perimeter of a rectangle is fifty centimeters. The length of the rectangle is twenty centimeters. What is the width of the rectangle?

Answer 1

the perimeter of a rectangle is the
length + length + width + width = 50

we know that the length is 25, so replace each length with 25 and solve for "width"

Answer 2

so 25+25= 50

Answer 3

i mean 20+20= 40

Answer 4

hmm sorry I was caught up on something

Answer 5

length = l
width = w

thus perimeter will be
l + l + w + w = 50

but we know that l = 20, thus
20 + 20 + w + w = 50
40 + 2w = 50

# solve for "w"

Answer 6

can you please just give me the answer this is the only question i have left on my test

Answer 7

I could but i don't see how that "helps" you

think about it this way, what if the teacher hands you out the test along with the answers too
what's the point of the test at all?

Answer 8

the idea behind exercises is not to trancribe material, so much it's to understand it

Answer 9

true :/ ah ok i'll try to solve it

Answer 10

20 + 20 + 5 + 5 = 50 so the answer is 5?

Answer 11

20 + 20 + w + w = 50
40 + 2w = 50

what if you subtract 40 from each side, the left and right side, what would that give you?
