Answer:
P = 50x + 11
A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)
Step-by-step explanation:
P =( the triangle - the shared side) +( the rectangular P - the shared side with the triangle )
P =2(6x - 4) + (14x +13) + 2 (12x +3)
P = 12x -8 + 14 x + 13 +24x +6
P = 50x + 11
Area = Triangle area + Rectangular area
T area = 1/2 base × hight
1/2 (6x-4) (6×-4)
= 1/2 (6x-4)^2
Rectangular Area = hight × length
= (12x +3 ) × (14x +13)
A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)
