The perimeter of the square will be equal to 48 millimetres.
<h3>What is the perimeter?</h3>
The perimeter is defined as the sum of all the sides of the given shape. For square, the perimeter will be the sum of all the sides of the square.
Given that a square with a length of 12 millimetres. The area of the square is marked as 132 square millimetres.
The perimeter of the square will be calculated as,
P = 4 x sides
The length of the square is 12 millimetres. For a square all the sides are equal.
The perimeter of the square will be calculated as,
P = 4 x 12
P = 48 millimetres
Therefore, the perimeter of the square will be equal to 48 millimetres.

Answer:
In bold below.
Step-by-step explanation:
(a) The largest angle is opposite the largest side.
So by the Cosine Rule:
8^2 = 4^2 + 6^2 - 2*4*6 cos x
cos x = (8^2 - 4^2 - 6^2) / (-2*4* 6)
= -0.25.
x = 104.48 degrees.
(b) Area of the triangle = 1/2 * 4 * 6 sin 104.48
= 11.62
= 3 √15.
(c) The shortest altitude will have the longest sides as the base.
Area = 1/2 * altitude * base
3√15 = 1/2 * 8 * a
a = 3√15 / 4 cm
= 0.75√15 cm.
Answer:
$3781.19
Step-by-step explanation:
Let us assume that the student has to earn $(1900 + x) by September 1 so that he can pay the $1900 tuition fee by September 1 and the remaining $x will grow at 3% simple interest to make him able to pay another tuition fee of $1900 by January 1.
So, we can write 
{Because September 1 to January 1 is 4 months and the monthly simple interest rate is 
%}
⇒ 1.01x = 1900
⇒ x = $1881.19 (Rounded to the nearest cents)
Therefore, the student has to earn $(1900 + 1881.19) = $3781.19 (Answer)
2.435 times or if it’s to the nearest whole number then it can go into it twice. 200+200= 400. It can’t go in 3 times because that would be 600.
