Answer:
17 cm²
Step-by-step explanation:
First I cut this figure into 2 rectangles. One big and small one. (the big one is on top of the small rectangle).
For the big rectangle, I multiplied its length by its width.
The area of the big rectangle: 3cm * 5cm = 15cm²
For the smaller rectangle, I also multiplied its length and width.
The area of the small rectangle: 1cm * 2 cm = 2cm²
Add up its areas: 15+2
To get 17cm² as your final answer
Answer:
15.6m
Step-by-step explanation:
FE is the hypotenuse, and we know the leg opposite of the angle, so we have to use the sin
sin = opposite/hypotenuse
hypotenuse * sin = opposite
hypotenuse = opposite / sin
FE = 10/0,64... = 15.6
To find the Least Common Multiple you first have to write down multiples of each number until one same multiple occurs in both lists. Once you find that multiple you can circle it to use it in your answer.
To find the greatest common factor you just have you list all the factors of that number and the other's too. Then you circle the largest factor that occurs in both lists.
