A path 1m wide is built along the border and inside a square garden of side 30cmfind the area of the path?
Let ABCD be the border of square garden of side 30m and the shaded region be the path Then AD = 30m , XP=1m, SY = 1m and XY = AD ⇒ XP + PS + SY = AD ⇒ PS = AD - XP - SY = 30m - 1m - 1m = 28m ∴ PQRS in a square of side 28m ∴ The area of path = Area of ABCD - Area of PQRS
Factor 4m to the 6th -30m to the 5 36m to the 4th?
2m4(m2-15m+18) i hope this is right! srry if its not i just did it for hw
What is the area of a circle with a diameter of 30m?
The formula for area of a circle is Pi x r (squared), A = Pi(rxr). So since the diameter is 30 you divide it by two and get 15 and then square it and multiply it by pi and get 706.86 meters.
What is the height of a solid with a volume of 120m cubed and a base area of 30m squared?
4m because V=BxHso H =120/30=4
A 1.5m wide footpath runs all along the fence outside a park 40m long and 30m wide What is the perimeter of the fence and what is the area of the footpath?
As two dimensions of the park are given, it can be assumed to be a rectangle in shape. → perimeter of fence = 40m + 30m + 40m + 30m = 140m For the area of the path, it runs along all the perimeter of the fence so its length is 140m and its width is 1.5m → the area of the footpath next to the fence is 140m x 1.5m = 210 m2. However, this area only includes the footpath that has one side next to the fence but excludes those parts of the footpath that go round the corners of the fence. As the path is given as 1.5m wide, it could be assumed that the path at each of the corners will be a quarter circle of radius 1.5m. As there are four of these quarter circles, their total area is the area of a whole circle: → area of the path = 210m2 + π x (1.5m)2 = 140m2 + 2.25π m2 ≈ 217.07 m2 The corners could also be squared off, so that each is a square of side 1.5m: → area of the path = 210m2 + 4 x (1.5m)2 = 219 m2.
What is the area of a 15m and 30m square?

What are the dimensions of rectangular lot if the perimeter is 90m and the area is 450m2?
The dimensions of the rectangular lot are: 30m by 15m
What is the gcf of 12m 15m and 30m?
The GCF is: 3m
15m plus 3 over 2 equals -6?
15m+3/2 = -6 30m+3 = -12 30m = -15 m = -1/2
What the perimeter of a square with 7.5m sides?
4*7.5 = 30m
A swimming pool 25m by 10m has a concrete border all round Find the area of the concrete border if it is 2.5m wide at the sides and 5m at the ends?
To find the area of the concrete border, we first calculate the total area of the pool including the border and then subtract the area of the pool itself. The total length of the pool with the border is 30m (25m + 2.5m on each side), and the total width is 15m (10m + 5m on each end). Therefore, the total area of the pool with the border is 30m x 15m = 450 square meters. The area of the pool itself is 25m x 10m = 250 square meters. Thus, the area of the concrete border is 450 square meters - 250 square meters = 200 square meters.
Mary wants to build a fence around her rectangular garden Its 10m wide and 15m longHow much fencing does she need to buy?
As the rectangular garden is 10m wide, then two sides will require 10m of fencing. Thus 2*10 = 20m of fencing. It is also 15m long, so two sides will require 15m of fencing. Thus 2*15 = 30m of fencing. Adding up all 4 sides => 20+30 = 50m of fencing.
If the length and breath of a rectangle are 20m and 15m then its perimeter is what?
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides of length 20m and two sides of length 15m. Therefore, the perimeter would be 2(20m) + 2(15m) = 40m + 30m = 70m.
What is the perimeter of a square with side lengths of 7.5 meters?
30 meters (7.5m x 4 sides = 30m)
Best time frame for day trading?
Day traders will usually use 1m, 5m, 15m or 30m time frames. Which time frame to choose is depends on the trader's character, an aggressive trader will probably use the 1m and 5m, a more serene trader will probably use the 15m or 30m.
What is the area of a rectangle with 30m length and 1m width?
