5 0

Answer:

40

Step-by-step explanation:

The number of girls is represented by 3 parts of the ratio.

Divide number of girls by 3 to find value of one part of ratio.

\frac{15}{3} = 5 ← value of 1 part of ratio, thus

5 parts = 5 × 5 = 25 ← number of boys

Total members = 15 + 25 = 40

Find the area of the following rectangle (the figure is not drawn to scale)
Sophie [7]

Answer:

<h2>204 units²</h2>

Step-by-step explanation:

It's a rectangle. Therefore the opposite sides are congruent.

We have the equation:

2x + 4 = 12              <em>subtract 4 from both sides</em>

2x = 8       <em>divide both sides by 2</em>

x = 4

Put the value of x to the expression 4x + 1:

4(4) + 1 = 16 + 1 = 17

Therefore we have the rectangle with dimesions 17 × 12.

The area of the rectangle:

A = (17)(12) = 204
