The formula for area a is height X average of the two parallel bases of the trapezoid. In this instance, a = 3[(7 + 5)/2] = 18 square centimeters.
If the area of a square is 49 square centimeters, the length of each of its sides are: 7 cm.
approximately 7 centimeters.
The area of a square is (side)2. Since side = 7 cm, then area = (7 cm)2 = 49 cm2 [square centimeters].
Area = 5*7 = 35 square inches
