Let's walk through this like we're solving it together in a tutoring session. From the image and the breakdown provided, we're working with a composite figure made up of rectangles and triangles. Here's how we approach it: Step 1: Perimeter We count all the outer sides: There are 8 sides that are 3cm long --> 8 x 3 = 24cm And 2 sides that are 5cm long --> 2 x 5 = 10cm So, the total perimeter is: 24 + 10 = 34cm Step 2: Area We break the shape into two parts: One rectangle: 3cm x 10cm = 30cm² Two right triangles: each is 3cm x 4cm --> Area of one triangle = 1/2 x 3 x 4 = 6cm² Two triangles = 6 x 2 = 12cm² So, the total area is: 30 + 12 = 42cm² Final answer: 34cm; 42cm² That matches the last choice in your list. Let me know if you'd like to try a similar one or explore how to break down more complex shapes!

For the perimeter, I am seeing 8 sides that are 3 cm and 2 sides that are 5 cm. So the total perimeter would be:


(8*3)+(2*5)

24+10 = 34 cm


For the area, area = length x width for rectangles. (the 2 triangles for one rectangle)

(3*4)+(3*10)

12+30 = 42 cm2


From the choices:

50 cm; 42 cm2

50 cm; 54 cm2

34 cm; 54 cm2

34 cm; 42 cm2
