Sagot :

Answer:

Step-by-step explanation:

a) To find the length of diagonal XT, we can use the distance formula to get [tex]\sqrt{(-3-5)^{2}+(4-(-2))^{2}}=10[/tex]

Since this is a rectangle, XT=YW, meaning YW=10 as well.

b) The area of a rectangle is given by length times width. The length is |-3-5|=8, and the width is |-2-4|=6. So the area is (8)(6)=48.

c) The perimeter is just 2(8+6)=28.
