Answer:
b=14
Step-by-step explanation:
A=1/2bh
We know A =126 and h = 18
126 = 1/2 b*18
126 = 9b
Divide each side by 9
126/9 = 9b/9
14 =b
Answer:
b = 14
Step-by-step explanation:
Substitute the given values for A and h into the formula
126 = [tex]\frac{1}{2}[/tex] × b × 18
126 = 9b ( divide both sides by 9 )
b = 14
