9cm because 9cm*9cm=81cm²
Hope this helps :D
Answer:
Step-by-step explanation:
Let's distinguish between point W and all of its reflections, shall we? The first reflection will give us W' and the second reflection will give us W''. When we begin with W at (-2, 3) we are 2 units left of the origin and 3 units up. If we reflect through the x axis, we are moving directly below the x-axis, 3 units to be exact. W' is located at (-2, -3). If we are to reflect this over the y-axis, we will move directly across from where the point is. W' is 2 units to the left of the y-axis, so we will move til we are 2 units to the right. W'' is located at (2, -3).
This would be a thing called reflection, transistion is when it moves, reflection is when it looks like it but either backwards or like looking in a mirror.
Answer:
m∠1=(180-110)=70°
m∠2=(180-115)=65°
m∠3= 65° because lines q and m are parallel
m∠4=115° because lines q and m are parallel
m∠5=(70+65)=(180-135)=45°
m∠6=45° because it is an alternate angle of m∠5
m∠7=(70+65)=(180-135)=45°

Answer: 140cm²
Step-by-step explanation:
Perimeter of a rectangle is calculated as: = 2(length + width)
where,
Length = x+4
Width = x
Therefore, perimeter = 2(length + width)
2(x + x+4) = 48
2(2x + 4) = 48
4x + 8 = 48
4x = 48 - 8.
4x = 40
x = 40/4
x = 10cm
The other side = x+4 = 10+4 = 14cm
Area = length × width
Area = 10cm × 14cm
Area = 140cm²
