What is the perimeter of a rectangle that has length 12m and width 3m?
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length is 12m and the width is 3m. Therefore, the perimeter would be 2(12m) + 2(3m) = 24m + 6m = 30m.
What is the height of a solid with a volume of 120m and base area of 30m?
120m^3/30m^2 = 4 meters
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.
What is the height of a solid that is 120m and a base area of 30m?
The question is so garbled that it is impossible to answer. What does 120 m refer to? A base area cannot be 30 m - area is measured in square units not linear units.
What is the perimeter of a hexagon if one edge is 5m?
The perimeter of the hexagon will be 30m (5m x 6 edges = 6 x 5 = 30m)
