Please answer question with work ♥️
vova2212 [387]

Answer:

r=201

d = 77 1/2

Step-by-step explanation:

6) First multiply left and right by 16, to get rid of the fraction:

r - 25 = 11*16

Now add 25 left and right:

r = 11*16 + 25 = 201


7) Add 5 left and right

2/5 d = 31

multiply by 5/2

d = 31 * 5/2 = 77 1/2

A square has a perimeter of 28 inches. Find the area of the square.
sasho [114]

Answer:

A = 49 in^2

Step-by-step explanation:

The perimeter of a square is found by

P = 4s where s is the side length

28 = 4s

Divide each side by 4

28/4 = 4s/4

7 =s

We want to find the area

A = s^2 where s is the side length

A = 7^2

A = 7^2

A = 49 in^2
