I can tell you how to work out 3)
so each side is 4 since 12÷3=4.
to work out the area you need the perpendicular height (line that goes through the middle of the triangle).
to do this you need SOHCAHTOA.
so in this case you use sine and angle is 60 since its an equilateral
sin 60=×÷4
x=sin 60 × 4
Answer:
Step-by-step explanation:
Given
--- Area of smaller rectangle
--- Area of bigger rectangle
Required
Determine the area of the areas.
The ratio is calculated by the dividing the areas of rectangles.
Substitute values for A2 and A1
Simplify the fraction
Represent as ratio
<em>Hence, the ratio of the rectangles is 1 to 9</em>
