Answer:
12 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (a + b)
where h is the perpendicular height and a, b the parallel bases.
Here A = 45, h = 5, a = 6 and b = ?, thus
45 = × 5 × (6 + b) = 2.5(6 + b) = 15 + 2.5b ( subtract 15 from both sides )
30 = 2.5b ( divide both sides by 2.5 )
b = 12
The measure of the other parallel side is 12 cm
The scientific notation for the number 1063 is 1.063×10³ after using the concept of fraction option (B) 1.063×10³ is correct.
<h3>What is the number?</h3>A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
The number is 1063
As we know the scientific notation can be written as:
1063 can be written as:
= 1063
= (1063/1000)1000
1.063×10³
Thus, the scientific notation for the number 1063 is 1.063×10³ after using the concept of fraction option (B) 1.063×10³ is correct.
