Answer:
174[tex]m^{2}[/tex]
Step-by-step explanation:
22 + 75 + 77 = 174
hope this makes more sense
so, I've divided the figure into 3 different rectangles
in order to get the surface area of the original figure, you'll need to figure out the surface areas of those 3 rectangles and then add them up
YELLOW RECTANGLE
the lenght is 11, the width is 2
in order to get the surface area, you'll need to multiply the length (11) by the width(2)
so you'll get
11 * 2 = 22
PURPLE RECTANGLE
the lenght is 15, the width is 5
in order to get the surface area, you'll need to multiply the length (15) by the width(5)
so you'll get
15 * 5 = 75
RED RECTANGLE
the lenght is 11, the width is 7
in order to get the surface area, you'll need to multiply the length (11) by the width(7)
so you'll get
11 * 7 = 77
THEN YOU JUST ADD UP THESE 3 SURFACE AREAS
you'll get 22 + 75 + 77 = 174
