height of shaded triangle -> hquestionable_i wrote:Can anyone help me with these questions? Thank you

height of big triangle -> 2h

Area of big triangle -> 1/2(b)(2h) =bh

Area of shaded triangle -> 1/2b(h) = 14

Area of unshaded part between the big triangle and shaded = bh-1/2bh =1/2bh = 14

Hence area of total unshaded part -> 14 x 2 = 28 cm2

Ans: (2)

P : B -> 5 : 29

29 = 5 x 5 + 4 = 5 x 4 + 9 = 5 x 3 + 14

Packets of 7 -> 2

Fraction is 2/5

Ans: (2)
