The median of the triangle is a segment that connects the vertex of the triangle to the midpoint of the side opposite to the vertex. <span>The altitude of the triangle is a segment that connects the vertex of the triangle to the side opposite to the triangle, which intersects that side at exactly 90°.</span>
First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.
Both ways are right ways. The perimeter is 90 meters.
Hope that helps!!
CONSECUTIVE NUMBERS; x, x+1
(x+1)4=3(x)+23
4x+4=3x+23
4x-3x=23-4
x=19
x+1=20
THEREFORE the consecutive numbers are 19&20
20/7 as a mixed number is 2 6/7
9/4 as a mixed number is 2 1/4
22/5 as a mixed number is 4 2/5
4/3 as a mixed number is 1 1/3
Given:
The length of a rectangle is 3 cm less than its width.
The area of the rectangle is 270 cm².
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then,

Area of a rectangle is:




Splitting the middle term, we get




Width of the rectangle cannot be negative. So, the only value of x is 18.



Therefore, the length of the rectangle is 15 cm and the width of the rectangle is 18 cm.
