Pls help me Like I rly need it now! And pls explain how you got the answer I will give 50 points.

12.5 units²

Step-by-step explanation:

Step 1: Draw a rectangle enclosing the shape and find it's perimeter.

The perimeter of a rectangle is all the sides added together.

P = 7 + 5 + 7 + 5 = 24 units².

Step 2: Determine the area of the triangles on the outside and add them together. There are 3.

Area of a triangle:  .

A = area

a = leg 1

b = leg 2

Triangle 1:

3 units²

Triangle 2:

3 units²

Triangle 3:

A = 2.5 units²

Step 3: Add them together and subtract the total from the perimeter of the rectangle.

Perimeter of rectangle - total area of triangles = perimeter of the shape in question.

24 - (3 + 3 + 2.5) = P

24 - 11.5 = P

12.5 = P

Now, there are other ways to do it, but this is the way I chose.

The answer is 12.5 units².

Now you're done!

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
