Question

HELP PLZ! I DONT GET THIS
The area of a rectangular piece of land is 280 square meters. If the length of the land was 5 meters less and the width was 1 meter more, the shape of the land would be a square.

Part A: Write an equation to find the width (x) of the land. Show the steps.

Part B: What is the width of the land in meters? Show steps.

Answer 1

if we call length=a and width=b then axb=280
then i can say that a-5=b+1 because it is a square now.
a=b+6 then (b+6) x b = 280
b^2 + 6b = 280
b=14

Answer 2

Thanks, so for part A i put this:
W = width of rectangle L = length of rectangle
L*W = 280
So we know that if we where to change the length to be 5 meters less therefore the width to be 1 meter more, they will be equal.
L − 5 = w + 1
but then I'd change l and w to a and b?

Answer 3

Then part B just show the work right?

Answer 4

And where did you get 6?

Answer 5

L-5 = W+1 so we can say L=W+6
L*W = 280 so we can change L and w+6 because they are equal.
(W+6)*W=280 W=14

Answer 6

Thank you!!
