1.)what is the perimeter of the shape?

12 feet

14 feet

26 feet

38 feet

2.)what is the perimeter of the shape?

30 inches

40 inches

60 inches

72 inches

Perimeter for first shape = 38 ft

Perimeter for second shape = 40 inches ..

Step-by-step explanation:

First we will define the perimeter.

The continuous line which forms the boundary of a closed geometric figure.

To find the perimeter of any geometrical shape the lengths of its outer boundary lines are added.

So for the first shape with sides 10ft, 4ft, 3ft and 9ft, we don't know the lengths of two sides

1. The side parallel to the 10ft side

and

2. The side parallel to 9ft side.

So the lengths of side will be:

For 1,

10-3 = 7ft

For 2,

9-4= 5ft

the perimeter will be:

=> 10+4+3+9+5+7

=> 38 ft

And for the second shape with sides 6 in ,5 in, 4 in, 3 in, 2 in and 10 in,

the length of one unknown side will be 6 inches as it is parallel and equal in length to the side with 6 in length,

And the length of side that is parallel to the side with length 4 inches will be same.

The perimeter will be:

=>6+5+4+3+2+10+6+4

=> 40 inches

So,

Perimeter for first shape = 38 ft

Perimeter for second shape = 40 inches ..

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
