    Question:-

    The perimeter of a rectangle is 36 cm. If its length is 10 cm, find its breadth.

    Answer:-

    Given:-

    \bullet Perimeter (P) of a rectangle is 36 cm.

    \bullet Length (L) of a rectangle is 10 cm.

    To Find:-

    Breadth (B) of a rectangle.

    Solution:-

    We know,

    P = 2(L + B)

    So,

    36 = 2(10 + B)

    36 = 20 + 2B

    36 – 20 = 2B

    16 = 2B

    B = 16/2 = 8 cm.

    Breadth (B) of a rectangle is 8 cm. [Answer]

    Answer:

    The perimeter of a rectangle is 36 cm, its breadth is 8 cm

    Step-by-step explanation:

    For a given rectangle

    Perimeter (P) = 36 cm

    length (L) = 10 cm

    Now,

    Perimeter (P) = 2 × (length + breadth)

    P = 2 × (l + b)

    36 = 2 × (10 + b)

    36 = 20 + 2b

    2b = 36 – 20

    2b = 16

    b = 16 ÷ 2

    b = 8 cm

    Thus, The perimeter of a rectangle is 36 cm, its breadth is 8 cm
