Find the area of the rectangle with measurements shown; reduce to lowest terms:
Length: 1 4/5 feet; Width: 1 5/8 feet
1 1/8 feet
2 37/40 square feet
1 5/40 square feet.
1 1/8 square feet

Answers

The area of the rectangle given is: B. 2 37/40 square feet.

What is the Area of a Rectangle?

Area of rectangle = length × width.

Given:

Length = 1 4/5 = 9/5 feet

Width = 1 5/8 = 13/8 feet

Thus:

Area of Rectangle = 9/5 × 13/8

Area of Rectangle = 117/40

Area of Rectangle = 2 37/40 sq. ft

Therefore, the area of the rectangle given is: B. 2 37/40 square feet.

Do 2 or more shapes with the same perimeter have to have the same area? Explain with examples. AND Do 2 or more shapes with the same area also have to have the same perimeter? Explain.

Answers

Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.

anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:

Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???

Answers

Answer:

For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.

Inverse operations are also very helpful for linear equations.

To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.

Ex:

13 - 2 = 11    (now change plus to minus)

13 + 2 = 11      (not the answer yet)

Now we switch the first number with the answer!

11 + 2 = 13

Hope this helped, I tried to explain it easily.

11+2=13 that’s the answer maybe
