Answer: 27
Step-by-step explanation:
45% is equal to .45.
.45 x 60 = 27.
If we multiply .45 by 60, we get 27. Therefore, Ahmed got 27 marks out 60.
If you want to check your answer, you can divide 27/60 to get .45.
Using the Heron's formula, the area of the triangle is: D. 95 square inches.
<h3>What is the Heron's Formula?</h3>
Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.
Given the following:
s = semi-perimeter = 1/2(50) = 25 in.
a = length of side a = 22 in.
b = length of side b = 13 in.
c = length of side c = 50 - 22 - 13 = 15 in.
Plug in the values
Area = √[25(25 - 22)(25 - 13)(25 - 15)]
Area = √[25(3)(12)(10)]
Area ≈ 95 square inches.

X is 10.5 because each side is the same and the other side is 42. So 42 divided by four is 10.5. Hope this helps!
Answer:
Option A will be correct.
Step-by-step explanation:
Given that polygon ABCD and polygon JKLM are similar.
Therefore, the corresponding sides of the two similar polygons will be in the same ratio.
Hence, 
Hence, we can write 
⇒ 
{Since given that CD = 3, DA = 6, LM = x and MJ = 59}
Therefore, option A will be correct. ( Answer )
