By definition a square has all 4 sides equal, the area of a square is sxs or s^2, so s^2 = 400, s = square root of 400 = 20. All sides will be equal to 20 m. The perimeter is the sum of the sides or 4 x s or 80.
Steps:
A= L^2
Where L is length of the side
400=L^2 》》》》》 square root
L= 20 all sides of square are 20 m
P = 4L
=4(20)
=80m
The number is 4 because: 8 x 4 = 32 + 5= 37
Of course you already know everything parallel sides are equals
therefore the value of each variables will be as following :
left side = right side
3y-6=24
3y=24+6
3y=30
y=30/3
y=10
-----------------------------------------------
5x+2=12
5x=12-2
5x=10
x=10/5
x=2
Answer:
The total surface area of the given shape is = 253.5
Step-by-step explanation:
Side of the square = 6.5 in
We know that area of the square is given by the equation
⇒ A =
Put the value of a in above equation we get
⇒ A = 6.5 × 6.5
⇒ A = 42.25
We know that the given shape has 6 surfaces so total surface area of the given shape is given by
⇒ = 6 × 42.25
⇒ = 253.5
Therefore the total surface area of the given shape is = 253.5
Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since and , we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since , we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
