a path 1 metre wide is built inside a square Park of side 30mm along its sides find the area of the path calculate the cost of constructing the path at the rate of RS 70per m²
Answers
Answer:
8120 rupees
Step-by-step explanation:
side of square park (A) = 30m
width of path = 1m
side of inner park (a) = 30-1-1 = 28m
cost of construction = 70 per m^2
Area of path = Area of square park - area of park inside the path
= A^2 - a^2
= 30^2 - 28^2
= 900 - 784
= 116m^2
Cost of construction of path = 70×116
=8120
Answer:
gn,
side of square park (A) = 30m
width of path = 1m
side of inner park (a) = 30-1-1 = 28m
cost of construction = 70 per m^2
Area of path = Area of square park - area of park inside the path
= A^2 - a^2
= 30^2 - 28^2
= 900 - 784
= 116m^2
Cost of construction of path = 70×116
=8120
