Answer:

The length of YZ is 22.30mm.

Step-by-step explanation:

Basically we need to find the hypotenuse of the triangle, or the longest side.

The formula for finding the hypotenuse of a triangle is: c = √(a² + b²)

First we need to multiply 14.3 and 17.1 to the second power.

14.30 × 14.30 = 204.49

17.10 × 17.10 = 292.41

Now we add our two sums.

204.49 + 292.41 = 496.90

Now we need to find the square root of 496.90, which is 22.2912539.

Rounded to the nearest DP(Decimal point), it's 22.30

PLEASE HELP!!!

Scilla [17]

You need the Law of Cosines here and you use it when you have 2 sides and an enclosed angle. The side across from the angle is the one we are looking for. The correct way to express the Law using what we have is the last choice above. Side RT is the unknown, and it is across from the angle that is enclosed between the 2 other sides.

Answer :

Length of rectangle = 14m

Width of rectangle = 12m

Explanation :

p = 2l + 2w = 68

l = w + 2

Substitute:

68 = 2(w + 2) + 2w

68 = 2w + 4 + 2w

4w = 64

w = 16

l = 18
