It depends on what the 4 measures given are! If they are the lengths of the sides of a parallelogram, the question cannot be answered.
Area = 1/2*(15+11)*7= 91 square units
1, 7, 11, 77
Surface area excluding the end caps = 7*pi*11 = 241.903 square units to 3 d.p.
To find the area of a rectangle, you multiply the base by the height. In this case, the base is 7 cm and the height is 11 cm. So, the area of the rectangle would be 7 cm x 11 cm = 77 square cm.
The area of triangle is : 38.5
A triangle with side a: 7, side b: 12, and side c: 11 units has an area of 37.95 square units.
It works out as: 5*8 = 40 square units
If you mean vertices of: (7, 3) (12, 3) (12, 11) (7, 11) then the area works out as 5 times 8 = 40 square units
38.5 Square units
38.5
The area of the rectangle works out as 7 times 6 = 42 square units
A square must have sides of the same length. It is not clear how 11 inches AND 7 inches can both refer to one square.
