Un mantel tiene las siguientes medidas: largo 48 cm y ancho es la mitad del largo A dicho mantel se le va a coser 2 vueltas de puntilla a su alrededor . ¿Cuántos m de puntilla se necesitan?

i believe the answer is 323 ft

step-by-step explanation:

$450 i think. hope this ☺

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
