The distance from the park to the grocery store is 0.9 mile.
Ezra runs 8 tenths of that distance and walks the rest of the way. The distance
ezra runs can be solve by multiplying 8/10 to the total distance.
X = 0.9(8/10)=0.72 mile
Answer:
2x^2+2x
Step-by-step explanation:
The large squares are x^2.
The rectangles are x
The small squares are 1
We have 2 large squares = 2x^2
and 2 rectangles = 2x
2x^2+2x
Check the picture below.
so.. simply, use the distance formula, to get their length an add them up, and that's the perimeter of the polygon.

so, those are their lengths, sum them all up, that's the polygon's perimeter.
The answer is 20.6 hope this helps
