[tex]\\ \tt\hookrightarrow A=14(1)+3(2)=14+6=20units^2[/tex]
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
