Question

The width of a rectangle is 12 units. Can the perimeter x of the rectangle can be 60 units when its length y is 18 units?

A:No, the rectangle cannot have x = 60 and y = 18 because x + y is less than 60
B:No, the rectangle cannot have x = 60 and y = 18 because x + y is less than 24
C:Yes, the rectangle can have x = 60 and y = 18 because x = 12 + 2y
D:Yes, the rectangle can have x = 60 and y = 18 because x = 24 + 2y

@Mehek14 can you help me please

Answer 7

so add up 18+18+12+12 to find the perimeter

Answer 8

60

Answer 9

correct so the perimeter can be 60

Answer 10

that means that you can eliminate A and B

Answer 11

ok

Answer 12

now the formula for perimeter is P = 2w + 2l
w = width
l = length

Answer 13

in your case length is y
so P = 2w + 2y

Answer 14

you know that the width is 12
so P = 2(12) + 2y
2*12 = 24

Answer 15

so your formula would be
x = 24 + 2y

Answer 16

So D

yes
