Answer:
area = length x half of length
Step-by-step explanation:
whatever the length of the rectangle is, replace it with 'length'
for example if the length was 6cm, it would be:
length x half of length = area
6cm x (6/2) = area
6cm x 3cm = area
18cm² = area
Let first even integer = 2x
2x + 2x+2 + 2x+4 + 2x+6 = 2O
8x + I2 = 2O
8x = 8
x = I
Therefore integers are; 2, 4, 6, 8
