    area of larger triangle = 1/2 (24)(15) = 12 x 15 area of smaller triangle = 1/2 (8)(5) = 4 x 5 solve those two areas then find the ratio

    the area of a triangle is \(\large \frac{bh}{2}\) you know that right?

    so that's how we got the area of the large triangle and the small triangle....the black line was the base (15 and 5) then the red ones were the height (24 and 8). The question is the ratio of the larger triangle to the smaller triangle so the ratio is lage triangle : small trianle -> \(\frac{\text{large triangle}}{\text{small triangle}}\) agree?

    \(\LARGE \frac{12 \times 15}{4 \times 5}\)
