2971 . The length of a rectangular hall is 5m more than its breadth. The area of the hall is 750m^2. The length of the hall is :

A. 15m
B. 22.5m
C. 25m
D. 30m

View Answer	Favorite Question

Answer: Option D

Explanation:

Hints : Let, tje breadth be b metre

b(b + 5) = 750

b2 + 5b - 750 = 0

b = 25, - 30

breadth = 25 meter and length = 25 + 5 = 30 meter

2972 . The length of a rectangular plot is 20 meters more than its breadth . If the cost of fencing the plot at TK. 26.50 per meter is TK. 5300, what is the length of the plot in meters?

A. 6
B. 100
C. 75
D. 50

View Answer	Favorite Question

Answer: Option B

Explanation:

Let length of plot = L meters, then breadth = L - 20 meters
and perimeter = 2[L + L - 20] = [4L - 40] meters
[4L - 40] * 26.50 = 5300
[4L - 40] = 5300 / 26.50 = 200
4L = 240
L = 240/4 = 60 meters.

A. Tk. 15,000
B. Tk. 15,550
C. Tk. 15,600
D. Tk. 16,500

Answer: Option D

Explanation:

In a right-angled triangle, you can use the Pythagorean theorem to find the length of the third side if you know the lengths of the other two sides. The Pythagorean theorem states:

c² = a² + b²

Where:

c is the length of the hypotenuse (the third side).
a and b are the lengths of the other two sides.
In this case, a = 5 cm and b = 12 cm. We want to find c:

c² = 5² + 12² c² = 25 + 144 c² = 169

Now, take the square root of both sides to find c:

c = √169 c = 13 cm

So, the length of the third side (the hypotenuse) is 13 cm.

এখানে, ত্রিভুজটির তৃতীয় বাহু হবে দুটি বাহুর যোগফল অর্থাৎ 7 + 11 = 18 থেকে ছোট এমন যেকোনো সংখ্যা। আবার সংখ্যাটি এমন হবে যেন ত্রিভুজের যেকোনো বাহুর যোগফল তৃতীয় বাহু অপেক্ষা বৃহত্তর হয়।
যেমন, তৃতীয় বাহু 4 হতে পারে না।
কারণ 7 + 4 = 11 হয়, যা অন্য বাহুর সমান।
সুতরাং তৃতীয় বাহু সর্বনিম্ন 5 হতে পারে, কারণ 7 + 5>11
⸫ ত্রিভুজটির সর্বনিম্ন পরিসীমা = 7 + 5 + 11 = 23.
