The median of a trapezoid is one half of the sum of the two sides. So EF is 1/2 (12+18) = 1/2 (30) = 15.

18 square inches is probably the area of the triangle, not the length of the base. The length of the base would be measured in inches (a unit of length), not square inches (a unit of area). So area = 1 / 2 * base * height = 18 square inches (given) height = 4 * base (given) 1 / 2 * base * 4 * base = 18 square inches 2 * base * base = 18 square inches base * base = 9 square inches base = 3 inches height = 4 * base = 4 * 3 inches = 12 inches Checking our work: height is 4 times the base (12 = 4 * 3) area is 18 (1/2 * 12 * 3).

a = (-2,3)b = (5,-4)vector AB = b - a = (7,-7)Length of AB = sqrt( 72 + 72) = sqrt(98) = 7*sqrt(2)Midpoint of AB = a + (b-a/2) = (-2,3) + (7/2,-7/2)= (3/2,-1/2)
The median of a trapezoid is one half of the sum of the two sides. So EF is 1/2 (12+18) = 1/2 (30) = 15.

By unit of length and distance and conversion ,we can say tha 1 ft=12 in 61 ft=12 * 61 in =12 * 61 /18 = =40.66 ft in 18 in
4... if you plug it in, it works
The length of a triangle with a height of 12 inches and an area of 18 square inches is 3 inches, since area is 1/2 * base * height. Therefore, 2 * area divided by height = 2 * 18 /12 = 3
we can create a graph with the x-axis representing the horizontal values and the y-axis representing the vertical values. let's determine whether the line segments AB and CD are congruent. The length of line segment AB can be calculated using the distance formula: AB = sqrt((x2 - x1)^2 + (y2 - y1)^2) For AB(0, 1) and CD(4, 1), the length of AB is: AB = sqrt((4 - 0)^2 + (1 - 1)^2) = sqrt(16 + 0) = sqrt(16) = 4 For CD(1, 2) and CD(1, 6), the length of CD is: CD = sqrt((1 - 1)^2 + (6 - 2)^2) = sqrt(0 + 16) = sqrt(16) = 4 Since the length of AB is equal to the length of CD (both are 4 units), we can conclude that line segments AB and CD are congruent.
18/12 = 3 : 2 or 1.5 : 1 or one and a half to one.

If you mean endpoints of (-1, -3) and (11, -8) then the length works out as 13
Area of Triangle= 1/2(ab) You must multiply length b and length a together and then half it.
18/12 = 12/12 + 6/12 12/12 = 1 6/12 = 1/2
If you mean endpoints (-1, -3) and (11, -8) then by using the distance formula the length between the points is 13 units
