The values of given questions are as follows.
What is Quadrilateral?A closed polygon with four sides, four vertices, and four angles is known as a quadrilateral. By joining four non-collinear points, it is formed. A quadrilateral's interior angles are always equal to 360 degrees when added together.
The words "Quadra," which means "four," and "Latus," which means "sides," are the source of the term "quadrilateral." It is not necessary for each of a quadrilateral's four sides to be the same length.
LEVEL 1
Fill in the blanks
a. Square
b. 180⁰
c. Equal and less than 180 degrees.
d. Rhombus
e. Trapezium
f. Rhombus
g. Rectangle
Name the following quadrilaterals
a. A parallelogram in which diagonals are equal, but adjacent sides are not equal is Rectangle.
b. A parallelogram with diagonals unequal, but bisect each other at 90⁰ is a rhombus.
c. A parallelogram in which adjacent sides are equal and diagonals are equal and bisect each other at 90⁰ is a Square.
LEVEL 2
Q2. one angle of parallelogram is 80⁰ to find remaining
we know for parallelogram sum of adjacent angles are equal and opposite angles are equal
let parallelogram ABCD
∠A = 80⁰ = ∠C
∠B = ∠D
∠A + ∠B = 180
80 + ∠B = 180
∠B = 100⁰
∠B = ∠D = 100⁰
Q3. angles of quadrilateral are in the ratio 1:1:3:4
let each angle be multiple of k
angles are k, k, 3k, 4k
sum of angles is 360⁰
k + k + 3k + 4k = 360
9k = 360
k = 40⁰
angles are
k = 40, k = 40, 3k = 3 x 40 = 120, and 4k = 4 x 40 = 160
40⁰, 40⁰, 120⁰ and 160⁰.
Q4. two angles of quadrilateral is 65⁰ each
let other two angles be x
sum of angles quadrilateral is 360⁰
65 + 65 + x + x = 360
130 + 2x = 360
2x = 360 - 130
2x = 230
x = 115⁰
other two angles are 115⁰ each.
Q5. perimeter of Rhombus = 40 cm
p = 4a
where a = side of rhombus
40 = 4a
a = 10 cm
and one diagonal is 12 cm
diagonals of rhombus bisect each other at 90⁰
Let rhombus be PQRS
and diagonals bisect at O
Since, triangle POQ is a right angled triangle,
PQ² = OP² + OQ²
OP = 12 / 2 = 6
OQ = SQ/2
PQ = 10
10² = 6² + (SQ/2)²
(SQ/2)² = 100 -36
(SQ/2)² = 64
SQ = 16 cm
length of Diagonal is 16 cm
Hence the solutions of Questions areas follows.

If a car travels 123 miles in 3 hours, how many miles will the car drive in 5 hours help?
Answer: 205 miles in 5 hours
Step-by-step explanation:
The way to find our answer is to first find how many miles the car can go in one hour. We would se the equation (123 divided by 3 to find our answer) which would give us 41 miles per hour. Then, we would proceed to multiply 41 by 5 which would give us our answer, 205 miles in 5 hours. Please correct me if I'm wrong!

Given that Height of the pencil = 12 centimetre
Now we have to find the area of the base of the prism means find the area of triangular part.
Volume of triangular prism is given by formula:
Volume of triangular prism = (Area of base) x (Height of the prism)
now plug the given values
216= (Area of the base) x 12
Area of the base
18= Area of the base
Hence final answer is 18 square centimetres.
