The formula for the area of a triangle is, A = 1/2b x h, where b is base and h is height. A = 1/2(18m) x 20m = 180m2 Another way to write the formula for the area of a triangle is A = (b x h)/2, which gives the same answer. A = (18m x 20m)/2 = 180m2

If C=18m then A = 25.783m2

Just add the 3 sides: 5+6+7 = 18m

25m x 6m x 18m = 2,700 cubic m

30m-7

The formula for the area of a triangle is A = 1/2b x h. A = 1/2*18m*20m = 180 m2

Area of traingle = Base * Height / 2 = 18*12/2 = 108 m2

18 * 2 = 36 / 2 = 18 m2

To find the area of a triangle, use the following formula:A = 1/2 ( b * h )whereas, variable b = base and h = height.A = 1/2 ( 18 * 20 )A = 1/2 ( 360 )A = 180 m3

The question cannot be answered because there is an error in the information provided. If the base of a rectangle is 18m, and the side is 20 m, then the area cannot be 108m. (It cannot be any number of metres since area must be measured in square metres, but that is another matter)

If C=18m then A = 25.783m2

216 square meters.

20*18 = 360 square meters (m2).
