A quadrilateral sometimes has one pair of parallel sides. Then the correct option is B.
What is a quadrilateral?
The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
If the quadrilateral has one pair of parallel sides is known as a trapezoid. And if the quadrilateral has two pairs of parallel sides is known as a parallelogram.
If all the angles are congruent then the parallelogram becomes a rectangle. And if all the sides are congruent then the parallelogram becomes a rhombus. If both sides and angles become congruent in the parallelogram then is known as a square.
A quadrilateral sometimes has one pair of parallel sides. Then the correct option is B.

Mathew is going to cover the patio with paving slabs. Each paving slab is a square of side 60cm.
Mathew buys 32 of the paving slabs.
A) Does Mathew buy enough paving slabs to cover the patio?
The paving slabs cost £8.63 each
B) Work out the total cost of the 32 paving slabs.
Answers
if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio and £276.16 is the total cost of the 32 paving slabs.
What is a Rectangle ?
A rectangle is a polygon with 4 sides , in which opposite sides are parallel and equal .
It is given that the patio has length of 3.6 m and width of 3 m
Each paving slab is a square having side 60 cm or .6 m
Area of a rectangle is given by
length * width
3.6*3
10.8 m²
Area = 10.8 m²
Area of a slab = 0.6 *0.6 = 0.36 m²
No. of slabs needed = n
10.8 = 0.36* n
n = 30 slabs
So if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio.
If the paving cost costs £8.63
The total cost for 32 slabs will be 32 * £8.63
= £276.16

P = Power in watts
V= Voltage in volts
I = Current in amperes
Since we are already given the power and voltage, simple substitution can be done.
P = VI
3.5 watts = 120 volts * I
I = 3.5 / 120
I = 0.0292 Amperes or 29.2 milliAmperes
Therefore, the current through the bulb is 29.2mA
