Answer:
Q2) total area = 132 cm²
Explanation:
Separate the shape into two rectangles by drawing a vertical line from the left endpoint of the 4cm line to the vertex below.
Area of a rectangle = width x length
Area of the left rectangle = 9 x 12 = 108 cm ²
Area of the right rectangle = 4 x 6 = 24 cm²
Total area = area of the left rectangle + area of the right rectangle
= 108 + 24
= 132 cm²
