Answer: 165in^{2}[/tex]
Step-by-step explanation:
rectangle : L x W

total area: 120+45= 
Answer:
Height = 20 ; Base = 5
Step-by-step explanation:
Triangle Area = Base x Height x 1/2
50 = 1x × 4x × 1/2
50 = 4x^2 × 1/2
50 = 2x^2
25 = x^2
x=5
Height equals to 4x -> 4 × 5 = 20
Base equals to x -> 1 × 5 = 5
