Question

Simple area and volume question

Answer 1

the base of this right triangle from the left part will be equal with sqrt(78^2 -77^2)
- than this will be =sqrt(6084 -5929) =sqrt155=12,44

- 68-12,44=55,56
- 55,56*77=4278,12 this is the rectangle area
- the traingle area =12,44*77/2 =6,22*77=478,94

- so area of parallelogramm =4278,12+2*478,94 =4278,12+957,88=5236

Answer 2

Thank you so far, at first I wasn't paying attention and mistook the plus sign for a comma so I was like, woah. That can't be right.

Answer 3

- so area of house =40*30=1200
- than 5236 --- 100%
1200 ---- x %
-----------------
x=1200*100/5236 = 22,91 %

- so than the house will covered 22,91% from area of the lot
