Answer:
Step-by-step explanation:
a) To find the length of diagonal XT, we can use the distance formula to get 
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.
No the vertex should be at (-3,-2) (I checked on my calculator)
Answer: The height of wall is 10.5 feet.
Step-by-step explanation:
Since we have given that
Number of bricks to build = 1470
Length of wall = 20 feet
We need to find the height of wall.
As we know that
Bricklayer's formula is given by

Hence, the height of wall is 10.5 feet.
