Answer:
10.5, , or
Step-by-step explanation:
To solve, you can use a variable (x) to represent the width.
The equation for area is A=L×W
So the Area is 820 and the length is 78.
820= 78w
Isolate the variable to solve.
w=10.5128....
If you round, it will be 10.5
10.5 as a fraction is or
52 in.
Let the width = x.
The length is x + 18.
perimeter = 2(L + W)
244 = 2(x + x + 18)
122 = 2x + 18
2x = 104
x = 52
The width is 52 in.
314in²
Given : Radius of the circle r=10 inches
A = 3.14 x 10²
A = 3.14 x 100
A = 314in²
20
When you add them all up and divide by seven, you get 20
c =7
