Question

A rectangle has a perimeter of 30 centimeters. Which of the following could NOT be the area for this rectangle?

B. 50 square centimeters
C. 54 square centimeters
D. 60 square centimeters

Answer 1

Answer 2

perimeter of rectangle = 2(l + w) = 30 so l + w = 15 length = l and width = w
area = l*w
if the l and w were approximately the same 15/2 get 7 and 8
9 and 6 area = 54
10 and 5 area 50
12 and 3 area
the area could not be 26

Answer 3

@triciaal 2 and 13 gives an area of 26

Answer 4

60 doesn't seem possible

Answer 5

why you say that

Answer 6

The greatest area will be when it's a square, so side length 7.5, which gives a max possible area of 56.25 cm^2, so anything below that is valid I think

Answer 7

@agent smith thank you I forgot the logic and then when substituting i did opposite \
@Firejay5 sorry correct answer as given by @agent0smith

Answer 8

is it A or D

Answer 9

d
the maximum area is 56 when the l = w so it cannot be 60
