Gaurav Seth 6 years, 3 months ago

area of quadrilateral ABCD = area of traingle ∆ABC + area of traingle ∆ADC

now use the formula,
area of ∆ = 1/2{x₁(y₂ - y₃ ) + x₂(y₃ - y₁) + x₃(y₁ - y₂)}

area of ∆ADC = 1/2 [ (-4) (-2 + 5) +(-4)( -5 - 5) + 5(5 + 2) ]
= 1/2 [ -4 × 3 + (-4) × (-10) + 5 × 7 ]
= 1/2 [ -12 + 40 + 35 ]
= 1/2 [ 28 + 35 ]
= 63/2 sq unit

again, area of ∆ABC = 1/2 [ -4 ( 7 + 5) + 0( -5 - 5) + 5 ( 5 - 7)]
= 1/2 [ -4 × 12 + 0 + 5 × -2 ]
= 1/2| [ -48 - 10]|
= 29 sq unit
now,
area of quadrilateral ABCD = 63/2 + 29
= 121/2 sq unit

Sia ? 6 years, 3 months ago

We know that, for any given set having m elements, the number of subsets can be represented as 2^m
According to the given condition,
2^m = 112 + 2ⁿ
{tex}\Rightarrow{/tex} 2^m- 2ⁿ = 112 = 128 - 16
{tex}\Rightarrow{/tex} 2^m- 2ⁿ = 2⁷ - 2⁴ (as 2⁷=128 and 2⁴= 16 )
On comparing both the sides,
2^m= 2⁷ and 2ⁿ = 2^{4

{tex}\therefore{/tex}} m = 7 and n = 4
