Answer:
W = 19 and L = 17
Explanation:
Let, length = L and Breadth = W
According to question,
2(L + W) = 72
L + W = 36
L = 36 — W………..(i)
And LW = 323
(36 — W)W = 323 [Putting the value of ‘L’]
W²—36W+323 =0
W²-2x Wx 18+(18)²— 1 =0
(w — 18)²— 1 = 0
(W— 13)² = 1
(W-18)² = ($\pm$1)²
W- 18 = 1
W= 1 + 18
W = 19
Putting the value of W in equation (1) we get
L = 36 – W
L = 36 – 19
L = 17.
Answer:
Take 10 note 60 pcs and Take 50 note 90 pcs.
Explanation:
Suppose Taka 10 note = p
Total Tk. = 10p Tk.
Take 50 note = (150 -p)
Total Tk = 50(150 —p) Tk
According to question
10p + 50(150 -p) = 5100
10p + 7500 – 50P = 5100
40p = 2400
p = 60
150—p=150—60=90
