and the height is 7 cm. Find the base.

Choose the correct answer from the selection below.

Answer 1

Answer:

Base = 16 cm

Step-by-step explanation:

Area of triangle is given by:

Area of Triangle = $\frac{1}{2}bh$

Where $b$ is the base and $h$ is the height.

The problem says that area is 56 ($A=56$) and height is 7 ($h=7$)

Plugging in the values we can solve for base:

$A=\frac{1}{2}bh\\56=\frac{1}{2}b(7)\\56=\frac{7}{2}b\\b=\frac{56}{\frac{7}{2}}=56*\frac{2}{7}=16$

Hence, the base of the triangle is 16 cm
