1 Answer

    • 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.
