Big triangle

13 yd, x yd
small triangle
3.25 yd, 4.23 yd.

To find the area of a triangle, you can use the formula:

Area = 1/2 * base * height

For the big triangle:
Base = 13 yd
Height = x yd

So, the area of the big triangle would be:
Area = 1/2 * 13 yd * x yd = (13/2) * x yd^2 = 6.5x yd^2

For the small triangle:
Base = 3.25 yd
Height = 4.23 yd

So, the area of the small triangle would be:
Area = 1/2 * 3.25 yd * 4.23 yd = (3.25/2) * 4.23 yd^2 = 6.88125 yd^2

no your suposed to find x

Apologies for the confusion. To find the value of x in the big triangle, we need additional information or measurements. Without that, we cannot determine the exact value of x.
