Answer the questions below. Write your answers in simplest form. (a) A square has an area of 144 ft . What is the length of each side?
(b) A square has a perimeter of 28 yd. What is the length of each side?

a) 12 ft for the length and the width

b) 7 ft as the length for each side

Step-by-step explanation:

a) Area = length x width

Since the shape is a square, that means that the length and the width have to be the same.

Because of this you have to square root 144 and you get 12 since 12x12 = 144.

b) For perimeter, this is the sum of all sides. Since a square has 4 sides and all these sides must be the same length since the shape is a square, then you have to do 28 ÷ 4 and you get 7 as your answer

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
