The perimeter is 120 cm
60cm
If all you need is the area of the base, the heigth is irrelevent. Length x Width = Area. Multiply 3.2 x 4.0 = 12.8 squared cm. The nearest squared cm is 13.
base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
Yes an area problem must have an squared unit. Suppose: Find the area of a suare with side 8 cm. Thus, 8 squared will be 64cm. Your answer will be 64 squared cm.

Area = Base*Height so Base = Area/Height = 720/15 = 48 cm
Multiply the base area by the height, and you have the volume.

Height = 8 cm

Area of a triangle = 1/2 * base * heightWe have,Area = 28 cm squared, base = 8cmthen,28 = 1/2 * 8 * h28 = 4*hh = 7cm
If you mean a rectangle, you don't have enough information. Area = base x height, there are many combination of numbers that give a product of 120. By the way, the area can't be 120 cm. It must be some square unit, such as square cm.
