Answer:
20ft^2
Step-by-step explanation:
The length is currently three feet, if you add two feet to three that makes five feet. Five times four is twenty.
I hope this helps!
To find the area, move each semicircle to fill up the square, you'll see there are three squares, each with an area of 4*4=16, so the total area is 3*16=48
Now the perimeter:
the perimeter of a circle is π times the diameter.
perimeter of each semicircle: (1/2)π*4=2π
there are altogether 6 arches and two straight sides, so the total is
2π*6+4*2=12π+8
the area is 48 square units, the perimeter is 12π+8 units.
U will take the two diagrams
And name them A N B
U then solve the triangle by triangle
The answer is A =80 because when u add 46+32 =78 and 78 round to the nearest ten is 80
Answer:
15 days
Step-by-step explanation:
Well, as you would be able to tell, you just have to find the LCM of 3 and 5. These do not have one before 3 x 5, so it is 15.
