Answer:

8 ft²

Step-by-step explanation:

Given 2 similar triangles with ratio of sides = a : b, then

ratio of areas = a² : b²

Here the ratio of sides = 2 : 3, thus

ratio of areas = 2² : 3² = 4 : 9

let x be the area of Δ EFG, then by proportion

$\frac{4}{x}$ = $\frac{9}{18}$ ( cross- multiply )

9x = 18 × 4 = 72 ( divide both sides by 9 )

x = 8

The area of Δ EFG is 8 ft²

Mr. Tally inherited $200,000. He used a portion of the inheritance to build a house. He invested the rest of the money for one y

Ivan

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Amount inherited = $200,000

Portion used to build house = h

Invested amount = 200,000 - h

1/3 of (200,000 - h) was invested at 12%

2/3 of 200,000 - h was invested at 15%

Interest from both investment = 8400

Cost of building =?

Using the simple interest formula :

Principal(P) * rate(r) * time

If the investment was for a year:

1st investment :

(200,000 - h)/3 * 0.12 * 1 = (24000 - 0.12h) / 3 = (8000 - 0.04h)

2nd :

(200,000 - h)*2/3* 0.15 * 1 = (20,000 - 0.1h)

Summing both :

8000 - 0.04h + 20,000 - 0.1h = 8400

28000 - 0.14h = 8400

-0.14h = 8400 - 28000

-0.14h = - 19600

= 140,000
