Answer:
63 inches
Step-by-step explanation:
the formula for the area of a triangle is
a = 1/2 bh
plug in the numbers
a = 1/2(9)(14)
9 times 14 is 126
a = 1/2(126)
half of 126 (or 126 divided by 2)
area = 63 inches
To do this without a calculator, it may be easier to break the number into smaller parts.
420 * 6
= (400 * 6) + (20 * 6)
= 2400 + 120
= 2520
Hope this helps! :)
