A triangle has side lengths of (8h – 9) centimeters, (4h + 5) centimeters, and (9k – 5) centimeters. Which expression represents the perimeter, in centimeters, of
the triangle?

sorry, i can't understand your question. will later if you describe more clearly!

: )

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
