Yes they do, Hope this helps :p
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:
x = -3, y = 5
Step-by-step explanation:
first, take the 3x + 17 = y and put it in place for the y in the second equation.
-3x=4x+17+4
then, solve the equation.
-3x=4x+21
-3x-4x=4x-4x+21
-7x=21
-7/-7x=21/-7
x = -3
substitute in other equation
4(-3) + 17 = y
-12 + 17 = y
y = 5
answers are x = -3 and y = 5
