    Answer:

    Step-by-step explanation:

    I think given figure is a rectangle and the upper portion is semicircle.

    (Next time kindly upload the picture taken from your book)

    Your answer :-

    Area of the entire rectangle = Length × Breadth

    Given length = 10cm

    Breadth = 14cm

    So area of entire figure = 10 × 14 = 140cm²

    Now we know that area of circle = πr²

    Since semicircle is half of a circle, its area = πr²/2

    Now if you closely see, the diameter of the semicircle is 14m

    So radius = 14/2 = 7cm

    So area = (πr²)÷2

    => area = (22/7 × 7²) ÷ 2

    => area = (22/7 × 49) ÷ 2

    => area = 154 ÷ 2

    => area = 77 cm²

    Now area of shaded portion = entire area – area of semicircle

    => 140 – 77

    => 63cm²

    So your answer is 63cm²

    Hope it helps dear friend ☺️✌️
