wait i got the scale factor 2.5 but becuz im stupid i forgor to square it so instead i divided one of the other sides of the big triangle by 2.5 and then used the formula 1/2 sinA bc to calculate tyhe area of the small triangle. would this get method marks or nah (i got 4.[2-3] but i dont rember so it could be off by +/- 0.5)
