Answer:
24 units^2
Step-by-step explanation:
bc=6
ab=8
area of a triangle: b*l/2
6*8/2=24
The gravity is 1.5m\s^2
Further explanation:
The weight of any object is given by the product of mass and gravity of the object
Let
m denote the mass of object
g be the gravity
and
w be the weight
Then the statement can be mathematically written as:
Given
m=300kg
w=450N
Putting the values of m and w into the formula
The gravity is 1.5m\s^2

Answer:
The ratios of their perimeters is 3/4
Step-by-step explanation:
In this question, we are asked to find the ratio of two perimeter of different regular polygons having the same number of sides but different side lengths.
A regular polygon is a polygon that has its all its sides to be of equal lengths. Now to find the perimeter of this kind of polygon, what we need to do is to multiply the number of sides that we have by the length of one of the sides.
Now, since we know that the number of sides of the polygons are equal, we can say that both polygons each have a total length of n sides each.
For the 6 inch side polygon, the perimeter of the polygon would be 6 * n = 6n inches
For the 8 inch side polygon, the perimeter of the polygon would be 8 * n = 8n inches
The ratio of the two thus becomes;
6n : 8n
This is same as writing 6n/8n
This is equal to 3:4 to the lowest ratio( we first divide by n on both sides, then 2 after wards to arrive at this answer.
