Problema Solution
A lawn is in the shape of a rectangle and and circle. How many pounds of grass seed are needed to plant the lawn if one pound covers 250 spauare feet? Round t 2 decimal places
L= 60ft.
w= 50ft.
cirlcle 10ft
Answer provided by our tutors
the area of the rectangle is A = l*w
A = 60*50
A = 300 ft^2
1 lbs covers 250 ft^2 and let x = lbs of seed we will need for 300 ft^2
1 : 250 = x : 300
x = 300/250
x = 1.2 lbs of seed
the area of the circle is A = r^2 pi, and the radius of the circle is 10 ft is given that is r = 10 ft
A = 10^2*pi
A = 100*3.14
A = 314 ft^2
1 lbs covers 250 ft^2 and let y = lbs of seed we will need for 314 ft^2
1 : 250 = y : 314
y = 314/250
y = 1.256 lbs of seed
