Answer:
8.5 units
Step-by-step explanation:
The distance between two points is given by
Taking points (-12, 11) and (-18, 17) as the first and second points respectively then
d=8.48528137423857 units
Rounded off to nearest tenths
d=8.5 units
Let us assume base of the window = b feet.
Height is 3 feet less than base, that is = (b-3).
Given area of the triangle = 20 feet square.
We know formula for area of a triangle:
Area = × Base × Height
Plugging values in formula, we get
20 =
Factoring quadratic, we get
=0
b+5=0
b=-5
b-8=0
b=8.
For base we can take only positive value.
<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>
