Question

I can find the perimeter and area of the rectangle

Answer 1

`P=38\\ A=72`

Explanation:

To find the perimeter (P), add up all of the side lengths of the figure:

(numbers in parenthesis are the unlabeled values in the figure).

`12+7+(8)+3+4+(4)=38`

To find the area of the figure (A), multiply the length and width of the original rectangle
`(12*7=84)`. Then, subtract this amount (84) minus the area of the missing rectangle in the top left corner
`(4*3=12)`.

Subtract the required values:
`84-12=72`.

Therefore, the perimeter of the figure is 38 units, and the area of the figure is 72 units.

Answer 2

A = 72, P = 38

Explanation:

Area can be found by getting the area of the overall figure, and then subtracting the blank space in the corner

12 * 7 = 84

3 * 4 = 12(invisible rectangle in top right)

84 - 12 = 72

Perimeter can be found by adding all of the sides

12 + 7 + (12-4) + 3 + 4 + (7-4)

The numbers in brackets are the unlabeled sides on the top and left.
