Answer:
15.65 foot
Step-by-step explanation:
Pythagoras theorem can be used
a² + b² = c²
a being 14b being unknown ( x )c being 21
hence,
14² + x² = 21²196 + x² = 441
x = √245
= 15.65 foot (answer)
Ok so, 42 ft. by 42 ft.
$25 per square yard
1 square yard = 9 square feet
The total square footage is 1,764 ft.
Total square yards is 196.
The total cost would be $4,900.
