14 one 15 6
Step-by-step explanation:
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:

Where,
are parallel sides and
is the vertical distance between the parallel sides.
Putting
in the above formula, we get




Therefore, the area of the trapezium is 408 square cm.
Answer:
option D
D. x = 5, y = 2
Step-by-step explanation:
Given in the question two equation,
Equation 1
5.3x + y = 28.5
Equation 2
4.2x + 3.1y = 27.2
rearrange equation 1 in terms of y
y = 28.5 - 5.3x
Substitute the value of y in equation 2
<h3>4.2x + 3.1(28.5 - 5.3x) = 27.2</h3>
4.2x + 88.35 - 16.43x = 27.2
4.2x - 16.43x = 27.2 - 88.35
-12.23x = -61.15
x = 61.15/12.23
x = 5
put value of x in any of the equation
<h3>5.3(5) + y = 28.5</h3>
y = 28.5 - 26.5
y = 2
She 56/92 6-5=1 and 567-1=566
2 1/2 + 2 3/5 =
2 5/10 + 2 6/10=
4 11/10 = 5 1/10
5 1/10 - 5 = 1/10
