Answer:
When finding the Area then the perimeter of a triangle with 8 base and height is 5 we find when rounded by 3 dp it will always be higher than square unit Area by 0.8 = 1 But this increases slightly as there are 2 sides when height is 8 - Therefore as proven perimeter will always be bigger than unit square when base is either larger or smaller than one another but if height is larger it will always have the larger perimeter as shown by 3dp as 0dp as shown is 22 units long when base is 5 and by 2dp - However when base is 8 the perimeter is 21 units long
Explanation:
Area of the triangle? A=1/2(base*height) Therefore 1/2 ( 8 * 5) = 20 unit squares or if base is 5 A = Therefore 1/2 ( 5 *8 ) / 2 = 20 unit squares shown another way but is the same. We are then asked to find the distance around the triangle? A = B *H / 2 Therefore if base is 8 and A is 20 then we are able to do pythagorus 1/2 * 8 = 4 and 4^2 + 5^2 = 16+25=41 and sq rt 41 = 6.4 sides Or if base is 5 and A is 20 then we are able to do pythagorus 1/2 * 5 = 2.5 and 2.5^2 + 8^2 = 6.25+64=70.25 and sq rt 70.25= 8.382 sides so the distance
around the triangle is either base when 5 = 5 +8.382+8.382=21.764 is more than unit squares when base is 5 and when the distance
around the triangle is either base when 8 = 8 +6.4+6.4 = 20.8 so due to the differene area will always be the sae but perimeter when rounded down to nearest -0.000 dp3 will always be bigger when base is either larger or smaller than one another but if height is larger it will always have the larger perimeter as shown by 3dp as 0dp is 22 units long when base is 5 and by 2dp when base is 8 the perimeter is 21 units long- What is one-half the product of the base
and the height? is shown always as Square Area of a triangle - RATIO'S when height is 5 we find that 8/5 also = 1.6 being the ratio difference where base is higher to begin with so as there are 2 sides the only reasoning of 0.8 / 0.6 = 1.33333333 = 1 1/3 so therefore as 8/5 * 1 1/3 = 6
/5= 1 and 1 1/5 = 1.2 proof is 1/5 of 8 =1.6 the Ratio and 1 stands for whole and 6 stands for 0.6 more = 6/10 larger base than smaller base - so we know 22/21 = 1/20 more and we know sides being 2 = (2)/6/10 = 1/20 so that is why as we find in proof the larger the height = shorter the base = 1/20 more in perimeter than one another when ratio is 1.6 for base and given height
