I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
The area of the first rectangle would be 18cm² and the area of the second rectangle would be 12cm².
<h3>How to calculate the area of a rectangle?</h3>
To calculate the area of a rectangle we must apply the following mathematical formula:
According to the above, to calculate the area of the rectangles we must multiply the length of the side by the base as shown below. We must also take into account the table that will give us the value of X that we do not know:
- 3cm × 6cm = 18cm²
- 2cm × 6cm = 12cm²
Finally, to know how much the area of both rectangles adds up, we add both values:
12cm² + 18cm² = 30cm²

it includes all the combinations.
Answer:
15. a 7.9 miles
b. NO .
Step-by-step explanation:
From the table, on
Monday = 3 2/5
Wednesday = 4 1/2
Write the distance in improper fractions as;
Monday = 17/5
Wednesday = 9/2
Find the sum as
where the L.C.M is 10
Answer is 7.9 miles
b.
Distance covered on Thursday and Saturday will be
2 2/6 + 3 3/4
14/6 + 15/4 ------the L.C.M is 12
(28+45)/12
73/12
The distance 73/12 miles for Thursday + Saturday is less than that of Monday + Wednesday 79/10 miles. The answer is NO.
