Answer:
Base = 16 cm
Step-by-step explanation:
Area of triangle is given by:
Area of Triangle = [tex]\frac{1}{2}bh[/tex]
Where [tex]b[/tex] is the base and [tex]h[/tex] is the height.
The problem says that area is 56 ([tex]A=56[/tex]) and height is 7 ([tex]h=7[/tex])
Plugging in the values we can solve for base:
[tex]A=\frac{1}{2}bh\\56=\frac{1}{2}b(7)\\56=\frac{7}{2}b\\b=\frac{56}{\frac{7}{2}}=56*\frac{2}{7}=16[/tex]
Hence, the base of the triangle is 16 cm
