9x1
You would add 2+7 which =9 then x+1 that’s 1 so it would be 9x1
1a. (15x9)+(9x24)
135+216
351 ft squared
1b. 30 bags
Answer:
l = 9p/4 , l = 9p/4
Step-by-step explanation:
Given:
Perimeter = 9p
Find:
Length and width
Computation:
Assume;
Length = l
Perimeter = 2(l+b)
9p/2 = l+w
w = 9p/2 - l
Area = lb
Area = l(9p/2 - l)
Using differentiation
l = 9p/4
w = 9p/2 - l
w = 9p/2 - 9p/4
w = 9p/4
When u times 28 by 32 you will get 896..I'm not sure if this is what u were asking for but if so here you go :)
