Both triangles are similar. The area of the smaller triangle is about 270 ft2. Which is the best approximation for the area of the larger triangle? small traingle side is 25ft the bigger traingle side is 35ft.
We know the relation between the area of similar triangles and the side length
=
area of the smaller triangle= 270 ft2
Let the area of bigger triangle =x
small traingle side=25ft
the bigger triangle side = 35ft
Ratio of sides is 25 : 35 that is 5:7
Now we make a proportion
=
270/x = 25/49
Cross multiply it
270 * 49 = 25 * x
13230 = 25x
divide by 25 on both sides
So x= 529.2
Area of larger triangle is approximately 530 square feet.
