Question

the area of a rectangle is 60 in.2 and the width is 4 in. what is the rectangle's length? can some one help me understand this?

Answer 1

4 * 2?

Answer 2

8

Answer 3

do you have any answer choices first of all?

Answer 4

15 in,
26 in
52 in

Answer 5

do you know the formula for the area of a rectangle is
L*W = Area
where L is the length and W is the width ?

Answer 6

the formula my teacher gave me for rectangle is: p=2l+2w and a=lw

Answer 7

they say width is 4 in
so W is 4

and
area of a rectangle is 60
so the area is 60

if we use the formula
W*L= area
4 * L = 60

that says 4 times a number is 60
(the number is the length)
which choice for L makes 4*L be 60 ?

Answer 8

if the width is 4 and the length is 15, what area do you get ?
can you do that ?

Answer 9

i got 15

Answer 10

yes
if the length is 15 and the width is 4, then the area is 4*15= 60
which matches the problem. this means the length is 15
