Answer 2

Answer: 10cm

Step-by-step explanation:

The area of the 4 pennants shown is 1600 cm

1600. To find the area of each pennant we can divide.

1600/4 = 400cm^2

Now we know the area and height of each triangle, so we can use those measurements to find the length of the base.

Area of a triangle= 1/2 x base x height

area of triangle= 1/2 x b x 80

                          400 x 40 x b

                             10 = b

The base of each pennant is 10cm.
