Answer: Option D

Explanation:

Let's denote the length of the rectangle as "L."

According to the given information, the width of the rectangle is 20 cm, and the diagonal is 8 cm more than the length, which can be expressed as:

Diagonal = L + 8

Now, we can use the Pythagorean Theorem to relate the length, width, and diagonal of the rectangle:

Diagonal^2 = Length^2 + Width^2

Plugging in the values we have:

(L + 8)^2 = L^2 + 20^2

Expanding and simplifying:

L^2 + 16L + 64 = L^2 + 400

Now, let's solve for L:

16L + 64 = 400

Subtract 64 from both sides:

16L = 400 - 64 16L = 336

Now, divide by 16:

L = 336 / 16 L = 21

So, the length of the rectangle is 21 cm.

Answer: Option C

Explanation:

ধরি, ইঞ্জিনিয়ার সংখ্যা = 3x
টেকনেশিয়ান সংখ্যা = 5x
3x + 5x = 120
8x = 120
x = 120/8
x = 15
টেকনেশিয়ান সংখ্যা = (15x5) জন = 75 জন।
