The perimeter of a rectangular garden is 160 m and its width is 30 m. Find the cost of leveling it at the rate of $2.50 per sq.m
nalin [4]

Answer:

$12,000.

Step-by-step explanation

Length of garden = 160 m

Width of garden = 30 m

area of rectangle = length * width

substituting vale of length and width for rectangular garden we have

area of rectangular garden = 160 m * 30 M = 4800 sq. m

cost of leveling one sq. m is $2.50

and it is required to level 4800 sq. m

hence to total cost to level rectangular garden = area of rectangular garden * cost of leveling one sq. m of space

=4800 * 2.5

= 12,000

Therefore cost of leveling rectangular garden is $12,000.

Monica paints 4/5 of a room in 30 minutes. If he continues at this speed,how many rooms will he paint in 4 hours?
AysviL [449]
The equation (4/5*2)4 will solve it because there are 60 minutes in 1 hour, and 2 times the thirty minutes gives us the hourly rate. The hourly rate (1.6 rooms) will then be multiplied to the 4 hours, to get 6.4 rooms painted in a matter of 4 hours. Answer= 6.4 rooms
