Video Solution

Solution Steps

00:00 Calculate the area of the triangle
00:07 BC equals two thirds of AE according to the given data
00:11 Substitute in AE's value in order to determine BC
00:15 Divide 9 by 3 to obtain 3
00:24 Apply the formula to calculate the triangle's area
00:27 (base(BC) x height(AE)) divided by 2
00:32 Substitute in the relevant values and calculate to find the area
00:37 Divide 6 by 2 to obtain 3
00:42 This is the solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the length of side BC using the given ratio.
  • Step 2: Find the area of the triangle using the area formula.
  • Step 3: Verify the solution with the provided choice options.

Now, let's work through each step:

Step 1: Side AE is provided as 9. Since side BC is 23\frac{2}{3} of side AE, we calculate:

BC=23×AE=23×9=6 BC = \frac{2}{3} \times AE = \frac{2}{3} \times 9 = 6

Step 2: Because triangle ABC is involved in calculation, the area of triangle BCE becomes Area=12×BC×height\text{Area} = \frac{1}{2} \times BC \times height, and assumed height perfectly completes these side lengths within the triangle grid. Given no specific height, the functional area equals set simplification calculations:

Substitute the values to find the area of triangle BCE:

Area of BCE=12×BC×AE=12×6×9 \text{Area of } \triangle BCE = \frac{1}{2} \times BC \times AE = \frac{1}{2} \times 6 \times 9

Calculate:

Area=12×54=27 \text{Area} = \frac{1}{2} \times 54 = 27

Therefore, the solution to the problem is 27 27 .
