The area of the rectangle is calculated by the formula:
S = a * b.
According to the condition of the assignment, the width of such a figure is 2 times shorter than its length, equal to 4 cm. Substitute the known values into the formula and write the expression:
S = 4 * (4: 2). According to the order of performing mathematical operations, first of all we find the values in brackets:
4: 2 = 2.
S = 4 * 2 = 8 cm².
