Q. Using suitable grouping find the product.

1. (-50)×187×(-2)

2. (-10)×6138×(-10)

3. 824×(-500)

0. Find the zeroes of the polynomial in each of the following,
(i) p(x)= x – 4
(ii) g(x)= 3 – 6x
(iii) q(x) = 2x

  2. [tex]\bf{\;\;\blue{Given :}} [/tex]

    Length = 17 cm

    Breadth = 15 cm

    [tex]\bf{\;\;\green{To \: find :}} [/tex]

    • Perimeter of rectangle

    [tex]\bf{\;\;\red{Solution :}} [/tex]

    L = 15

    H = 17

    L² + B² = H²

    [tex]\bf{\;\;\blue{ =) \: (15) {}^{2} + B {}^{2} = (17) {}^{2} }}[/tex]

    [tex]\bf{\;\;\blue{ =) \: 225 +B {}^{2} = 289 }} [/tex]

    [tex]\;\;\bf{\;\;\red{ =) \: B {}^{2} = 289 – 225}} [/tex]

    [tex]\;\;\bf{\;\;\red{ = ) \: B {}^{2} = 64}} [/tex]

    [tex]\;\;\bf{\;\;\green{ = ) \: B = \sqrt{64} }} [/tex]

    [tex]\;\;\bf{\;\;\green{ = ) \: B = 8 \: cm}} [/tex]

    Breadth = 8 cm

    Area of rectangle = L × B = 15 × 8 = 120m²

    [tex]\sf Perimeter \: of \: rectangle \: = 2 ( L + B ) [/tex]

    [tex]\sf = 2 ( 15 + 8 ) \\ \sf= 2 ( 23 ) \\ \sf= 46 cm [/tex]

    Hence , the answer is 46 cm .
