The width of a wall is 22m and its height is 3.5m How many bricks of length 22cm and width is 7 cm can make a single wall?
Width = 22m Height = 3.5m --- Convert both of these into cm to convert into same units Width = 22 x 100 = 2200cm Height = 3.5 x 100 = 350cm Next find the area of the wall ---Area of rectangle = height x width Area of the wall = 2200 x 350 = 770,000 sq. cm Now for the bricks Length = 22cm Width = 7cm Area = 22 x 7 = 154 sq.cm To find the number of bricks needed we have to divide the area of the wall with the area of one brick 770,000 / 154 =5000 Therefore 5000 bricks are needed to make a single wall
What is the area of four walls of the room?
It depends on the measurements of the walls or how long they are.If the room was square, and each wall measured 2metres, then you multiply the measurements of two sides together to find the area - 2x2=4m2.If it was a rectangular room measuring 2m on two sides and 4 on two sides, multiply 2x4 which equals 8m2.Remember, the formula for working out area or a square or rectangle is length x width.

The Ups and Downs of an Electric Wall Heater?
An electric wall heater is the perfect solution for houses in areas that have mild winters. The heater will provide heat for the rooms around it, and it should be installed on a wall that is central to the whole house. Electric wall heaters have some good features and some bad features. Targeted Heat Usually an electric wall heater is a panel that runs from just below the ceiling to just above the floor. It radiates heat to all of the air that directly surrounds it. If you need to heat a three bedroom house, an electric wall heater may not have the strength to reach every room. If your house or apartment is smaller, however, an electric wall heater may be just what you need to keep a couple of the bedrooms and the bathroom warm. Where you place the heater will have a definite impact on how well it heats your rooms. Uses Less Electricity than Central Heating Central heating is designed to heat your entire house. It uses the thermostat to determine when to turn off and on, and it pushes warm air into every room through a ducting system. An electric wall heater doesn’t attempt to warm the entire house. It only warms the air in a radius around the heater. Heating is more immediate with an electric wall heater, so you don’t have to wait hours for it to heat the room. Since you have tighter control over when an electric wall heater is off or on, the heater consumes less electricity and delivers targeted heat when you need it. Easy to Control An electric wall heater is a very straightforward device. When the house is cold, all you have to do is turn it on. The room will start to get warmer immediately. When a room is too warm, all you have to do is turn off the wall heater and the room will begin to cool immediately. The air around an electric wall heater is not pushed around the room, so it remains warmer than if it were blowing through a vent. Electric wall heaters become very hot when they are in use, so keep children a safe distance away from the heater.
