Answer:
Step-by-step explanation:
P = 2(L + W).....perimeter of a rectangle formula
P = 20
L = 2W + 1
20 = 2(2W + 1 + W)
20 = 2(3W + 1)
20 = 6W + 2
20 - 2 = 6W
18 = 6W
18/6 = W
3 = W <==== the width is 3 inches
L = 2W + 1
L = 2(3) + 1
L = 6 + 1
L = 7 <===== the length is 7 inches
area triangle:
b×h/2
= 11 in×10 in/2
=55 in²
area half-circle:
pi×r² /2
= 3.14×5in² /2
=78.5in² /2
=39.25 in²
Total area: area triangle+ area half-circle
= 55 in²+39.25 in²
=94.25 in²

Answer:
6x - 24.
Step-by-step explanation:
Distributive Property is:
a(b + c)
= ab + ac
So for this expression
6(x - 4)
= 6*x + 6 * -4
= 6x - 24.
