Find the perimeter of the isosceles trapezoid

Genrish500 [490]

Answer:

A =136 cm^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) *h where b1 and b2 are the lengths of the bases and h is the height

A = 1/2( 22+12) *8

A = 1/2 ( 34)*8

A =136 cm^2

WE has endpoints at<br>W(10, 2) and E(5, -3).<br>How long is WE?

s2008m [1.1K]

Answer:

$WE=5\sqrt{2}$

Step-by-step explanation:

Distance between two points:

The distance between $(x_1,y_1)$ and $(x_2,y_2)$ is given by $=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2$

Hence distance between $W(10,2)$ and $E(5,-3)$

$WE=\sqrt{(5-10)^2+(-3-2)^2}=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}\\\\WE=\sqrt{50}=5\sqrt{2}$
