Perimiter is adding up all sides A+B+C+D.
Rectangles have two sets of parallel lines the height and the width.
If we know one of the heights is 7 the. We can conclude the parallel side is also 7
So then the total perimiter 34 minus the heights is 20.
We know that there is another set of parallel sides, remaining and 20 is how perimiter is left
… so if you divide by 2 your left with one side which is the width
Answer 10
Answer:
132 ft squared
Step-by-step explanation:
One way is to divide the shape into a rectangle and a triangle, by drawing a vertical line.
This gives a rectangle that is 9 by 11, so has area 99.
The triangle has a base of 11 and height of 15 - 9 = 6.
So the area of the triangle = 1/2 x b x h = 1/2 x 11 x 6 = 33
So the total area is 99 + 33 = 132.
There was a 9 dollar tip.
Hope this helps.
That's actually pretty easy so since a cube has 6 faces and all the sides are equal you just have to multiply 12x12 whic equals 144 times 6 which is 864
so 864mm to the second power
1. 1.5 and 3.5
2. both equations because they share these particular points
