Question

I can find the perimeter and area of the rectangle

Answer 1

Answer:

$P=38\\ A=72$

Step-by-step 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

Answer:

A = 72, P = 38

Step-by-step 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.
