1The area is 10.5 cm2.
x =
Solution
A=1/2bh (one half base times height)
10.5 cm2 = 1/2(x * 3cm)
21 cm2 = x * 3cm
7 cm = x

2The area is 12.5 in2.
x =
Solution
A=1/2bh (one half base times height)
12.5 in2 = 1/2(5in * x)
25 in2 = 5in * x
5 in = x

1A triangle has an area of 72 yd2. The height is 12 yd. What is the length of the corresponding base?
base =
Solution
A=1/2bh (one half base times height)
72 yd2 = 1/2(b * 12yd)
144 yd2 = b * 12yd
12 yd = b

2A triangle has an area of 78 cm2. The length of one side is 13 cm. What is the corresponding height?
height =
Solution
A=1/2bh (one half base times height)
78 cm2 = 1/2(13cm * h)
156 cm2 = 13cm * h
12 cm = h
