Answer:
A = about 62.82
Step-by-step explanation:
A=lw+l(w/2)2+h^2+w(l/2)2+h^2=4·4+4·(4/2)^2+5.5^2+4·(4/2)^2+5.5^2≈62.82
The answer is True. In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Answer:
4x − 10
Step-by-step explanation:
The width of rectangle A is 2x+4 and the length of rectangle A is x-1. This makes the perimeter
2(2x+4)+2(x-1)
= 4x+8+2x-2
= 6x+6
The width of rectangle B is 3x+1 and the width of rectangle B is 2x-3. This makes the perimeter
2(3x+1)+2(2x-3)
= 6x+2+4x-6
= 10x-4
Subtracting Perimeter B - Perimeter A, we ahve
(10x-4)-(6x+6)
= 10x-4-6x-6
= 4x-10
