<em><u>Question:</u></em>
How fast should the ant walk to go around the rectangle in 4 minutes if the sides are 12 inches and 16 inches
<em><u>Answer:</u></em>
The ant should walk 14 inches per minute
<em><u>Solution:</u></em>
Given that,
Dimensions of rectangle are 12 inches and 16 inches
<em><u>Find the perimeter of rectangle</u></em>
Perimeter = 2(length + width)
Perimeter = 2(12 + 16)
Perimeter = 2(28) = 56
Thus perimeter of rectangle is 56 inches
Time taken = 4 minutes
We have to find the speed at which ant covers 56 inches in 4 minutes
<em><u>The speed is given by formula:</u></em>


Thus the ant should walk 14 inches per minute

<u>Given</u>:
Let A denote the angle of the given triangle which measures ∠A = 81°
Let B denote the angle which measures ∠B = 40°
The length of the side a = x.
The length of the side b = 7 cm.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the law of sine formula.
Applying the law of sine, we have;

Substituting the values, we have;

Simplifying, we get;

Cross multiplying, we have;



Thus, the length of the side x is 10.8 cm.
