Answer:
5cm
Step-by-step explanation:
Given area of trapezium = 31.5 sq. cm
Length of parallel sides = 7.3cm and 5.3cm
Formula to calculate area of trapezium is
1/2*(sum of parallel sides)*perpendicular distance between parallel sides
sum of parallel sides = (7.3 + 5.3) = 12.6cm
substituting value of area given and sum of parallel sides we have
31.5 = 1/2* 12.6 * perpendicular distance between parallel sides
(31.5 * 2)/12.6 = perpendicular distance between parallel sides
perpendicular distance between parallel sides = 63/12.6 = 5
Therefore perpendicular distance between parallel sides for given trapezium is 5cm.
<span>We are given the slope and the y-intercept.
m=-6/7, b=3 1/7
We use the slope-intercept form of the equation of the line to get an equation.
y = mx + b
y = -6/7x + 3 1/7
Now we need standard form.
The x- and y-terms must be on the left side, and we need integer coefficients.
y = -6/7x + 22/7
Multiply both sides by 7.
7y = -6x + 22
Add 5x to both sides.
6x + 7y = 22

The ratio of their surface areas will be a²/b². And the ratio of their volumes a³/b³.
<h3>What are the
surface area and the volume of an object?</h3>
The size is the amount of space covered by a two-dimensional hard surface.
The volume of an element or compound is the sufficient space it takes up, calculated in cubic units.
1. The ratio of the surface area of similar solids
If the ratio of the corresponding edge lengths of two similar solids is a:b, then the ratio of their surface areas will be a²/b².
2. The ratio of the volume of similar solids
If the ratio of the corresponding edge lengths of two similar solids is a:b, then the ratio of their volumes a³/b³.
More about the surface area and the volume link is given below.
