12ft by 21ft is equal to 4m by 7m or 28 square meters.
The area of a decagon with a side of 4m is 123.1m2
well if you add it it is easy. A:11m.The above is a load of bovine droppings. P = 2(L + W) so the CORRECT answer is 22 m.The perimeter of a rectangle is 2 x (length + width).2 x (7m + 4m) = 2 x 11m = 22m
Base 7m area 49 m2
4m2
um i think you multiply them
Assuming these measurements are in pairs 10m x 10m is 100m2 6m x 4m is 24m2 7m x 3m is 21m2 Total 145m2
-(4m + 3)(5m - 2)
4/7 - 4/m need a common denominator--multiply the first term by m/m and the second by 7/7 4m/7m - 28/7m (4m-28)/7m OR 4/7 - 4/m
4m + 3m = 180 7m = 180 m = 25 5/7

The area of 4m by 4m is 16 square meters.
A triangle with two equal sides is an isosceles triangle and you can have as many as you like.
7*8*4 = 224 cubic metres.
12ft by 21ft is equal to 4m by 7m or 28 square meters.
Rectangle with area 28 m2 and width = 4 m => length = 28/4 = 7m. Then, perimeter = 2*(4+7) = 2*11 = 22 metres.
The area of a decagon with a side of 4m is 123.1m2
