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)

Answer:
B
Step-by-step explanation:
1 is 100% so increasing it by 12% means adding 0.12 to it
Since A = bh
and A = 198 and b = 18?
h = A/b
= 198/18
= 11
