 Please prefer the picture for your answer.
 We know, area of a ∆ = 1/2 × base × height.
 Here, base = ( 7 + 1) units = 8 units.
 Height = (7  1) units = 6 units.
 Therefore, the area of the ∆
 = (1/2 × 8 × 6) square units
 = 24 square units.
Answer:
The area of the triangle is 24 square units.
Hope you could get an idea from it.
