Answer:

x = 3

y = 9

Step-by-step explanation:

\frac{x}{y} =\frac{1}{3}    →  ( 1 )

  • Use cross multiplication to the above equation.

3x = y   →  ( 2 )

x + y = 12 → ( 3 )

  • Now you can put 3x instead of y to equation (3) according to equation (2).

<u>Let us solve.</u>

x + y = 12

x + 3x = 12

  • And now you can solve the above equation and find the value of x.

4x = 12

Divide both sides by 4.

x = 3

  • Now we can put 3 instead of x to any equation here and find the value of y.

<u>Let us take equation ( 2 )</u>

3x = y

3 × 3 = y

9 = y

Hope this helps you :-)

Let me know if you have any other questions :-)

Find the ratio of the known sides.

6/4 = 1.5

The larger triangle is 1.5 times larger than the smaller one.

Area is in square units, so to find the area of the larger triangle square the ratio and multiply that by the area of the known triangle.

1.5^2 x 40 = 90 square cm.
