Lynn street, Allen street, and route 11 form the boundaries of a triangular forest, as shown in the map below.

There are 2 triangles there. So the formula for a triangle is BxH/2. So base of 36km x 15km = 540/2= 270km squared. Then the second triangle 20km x 15 km=300/2=150km squared. Next add the two triangles together so 270km squared + 150km squared= 420km squared. 420km squared is your answer

Do you remember how to find the area of a triangle ?
Is the area (1/2) (base) x (height) ?
On the map, the base and the height are conveniently labeled for you. The base is (20 + 36) = 56 km, and the height is 15 km.
I'm sure you can handle it from there, and earn yourself 5 points.

To find the total area of a triangular forest formed by three streets, we can break it into two triangles. For the first triangle, with a base of 36 km and height of 15 km, the area calculates to 270 km²; for the second, with a base of 20 km and height of 15 km, the area is 150 km². Adding these gives a total area of 420 km².
