First solve the length of side BC, CD, EF and FA
Since BC = CD = sqrt( 10^2 + 10^2)
BC = CD = 14.1421
FA = EF = sqrt(10^2 + 20^2)
= 23.3607
So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607
= 93
The area is made up be triangle FAE, rectangle ABDE and
triangle BCD
A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)
<span>A = 500 sq units</span>
Answer:
The conclusion is "Plane R and Plane S form a line if they intersect."
Step-by-step explanation:
Consider the provided statements.
1) If two planes intersect, their intersection is a line.
2) Plane Rand plane S intersect.
- If two points lie in a plane, then the line joining them lies in that plane.
- If two planes intersect, then their intersection is a line.
For better understanding refer the figure:
There are two planes R and S, which intersect at the line l.
Since the given two planes intersect, the using the above fact we can say that their intersection is a line.
Thus, the conclusion is "Plane R and Plane S form a line if they intersect."
