Calculate the areas of the rectangle
8 cm
3 cm

Rectangle A: 22 cm

Rectangle B: 25.8 cm

Step-by-step explanation:

To find the area, we multiply the size of the two sides.

8 x 2 = 16

3 x 2 = 16

Now, we have to add 16 and 6.

16 + 6 = 22

To find the area, we multiply the size of the two sides.

5.2 x 2 = 10.4

7.7 x 2 = 15.4

10.4 + 15.4 = 25.8

The answers are:

Hope this helps!

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
