B(You survey every 10th student entering school to find out the amount of time it takes them to get to school) is a good survey
Answer:
Area of the fig. = 127 yards^2
Step-by-step explanation:
So,Seeing carefully we see 3 figures : 2 rectangles & 1 square,
So, first of all Area of the Big Rectangle
Area of the rectangle = l*b
length = 13 & breadth = 9
= 13*9
= 117 yards^2
Now, Area of the small rectangle
Length & Breadth = 3 & 2
Area = 3*2
= 6 yards^2
Area of one and only square in the fig.
= S*S (side = 2)
= 2*2
= 4 yards^2
Total area of whole fig. = (117 + 6 + 4) yards^2
= 127 yards^2
Hope it works!
