a rectangle measures x + 7m long and x + 4m wide.what is its area?

Sagot :

Answer:

Area = Length * Width

Volume = Length * Width * Height

As you can likely already see, we have a problem. The question asks for “area” but gives a measurement for Length, Width, and height.

So the best I can do is give the answer of the total “Surface area” of the room.

Floor = 12m * 7m = 84m^2

Roof = 12m * 7m = 84m^2

Front/Back walls (x2) = 7m * 4m * 2 = 56m^2

Side walls (x2) = 12m * 4m * 2 = 96m^2

Total surface area

= 84m^2 + 84m^2 + 56m^2 + 96m^2

= 320 m^2

Step-by-step explanation:

To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
