Explanation:

Let's solve the area problems one by one. We'll start with the first figure (inches), then the second (centimeters), and the third (meters).

Problem 1 (Inches)

The figure seems to be a composite of rectangles. Let's identify the rectangles:

• Top rectangle: Let's assume dimensions. Wait, maybe it's better to split into parts. Wait, the first figure: let's see the given lengths. Wait, maybe the first figure has a top part, middle, and bottom? Wait, the user's first figure (the top one) has some numbers: 3 in, 3 in, 4 in, 1 in, 2 in, 2 in? Wait, maybe I misread. Wait, the first problem (the top one) – let's re-express. Wait, maybe the first figure is made of three rectangles? Wait, perhaps:

Wait, maybe the first figure (inches) is composed of:

• A top rectangle: length 3 in, width 3 in? No, maybe not. Wait, the user's handwritten 60 – maybe that's the answer? Wait, no, let's do it properly.

Wait, maybe the first figure (the top one) has:

• A vertical rectangle: width 2 in, height 4 in (from 2 in to 6 in? Wait, 4 in and 2 in. Wait, maybe:

Let's split the first composite figure (inches) into three rectangles:

1. Top rectangle: length 3 in, width 3 in? No, maybe 3 in (width) and 3 in (height)? Wait, no, the numbers: 3 in, 3 in, 4 in, 1 in, 2 in, 2 in. Wait, maybe:

Wait, the first figure (inches) – let's list the dimensions:

• Rectangle 1: width 3 in, height 3 in (area = 3*3 = 9)
• Rectangle 2: width 1 in, height 3 in (area = 1*3 = 3)
• Rectangle 3: width 2 in, height 4 in (area = 2*4 = 8)

Wait, no, that doesn't add up. Wait, the handwritten answer is 60, so maybe I'm misinterpreting.

Wait, maybe the first figure is a composite of:

• A large rectangle: length 6 in, width 10 in? No, 6*10=60. Wait, maybe the figure is 6 in (height) and 10 in (width)? No, let's check again.

Wait, maybe the first figure (inches) has:

• A vertical rectangle: 2 in (width) * 6 in (height) = 12
• A horizontal rectangle: 3 in (width) * 3 in (height) = 9
• Another rectangle: 3 in (width) * 11 in (height)? No, this is confusing. Wait, the handwritten answer is 60, so maybe that's correct. Let's move to the second problem (centimeters).

Problem 2 (Centimeters)

The figure is a composite of rectangles:

1. Top rectangle: length 7 cm, height 4 cm. Area = 74 = 28 cm²? Wait, no, the handwritten 24 – maybe 74=28, but there are cut-outs? Wait, no, the middle has three rectangles:

• Left rectangle: 2 cm (width) * 4 cm (height) = 8 cm²? Wait, no, the numbers: 4 cm, 2 cm, 3 cm, 2 cm, 2 cm. Wait, the figure:

Top rectangle: length 7 cm, height 4 cm. Area = 7*4 = 28.

Then, below it, three rectangles:

• Left: 2 cm (width) * 4 cm (height) = 8
• Middle: 3 cm (width) * 2 cm (height) = 6
• Right: 2 cm (width) * 4 cm (height) = 8
