Answer:

1 = 2 units

2 = 4 units

P = 36 units

A = 20 units²

Step-by-step explanation:

1. PART A:

Missing length 1 = 14 - 12 = 2 units

Missing length 2 = 1 + 3 = 4 units

PART B

The perimeter is the distance all the way around the outside of a 2D shape. To work out the perimeter, add up the lengths of all the sides

Perimeter = 1 + 12 + 3 + 2 + 4 + 14 = 36 units

PART C

Area of a rectangle = width x height

Separate the shape into 2 rectangles (so draw a line down from the internal corner of the L shape).

Total area = 1 x 14 + 2 x 3 = 14 + 6 = 20 units²
