Question

If the area of a triangle is $10c{m}^2$ and its height measures 5 cm, then the length of the corresponding base is .

• A. 4 cm
• B. 6 cm
• C. 8 cm
• D. 5 cm

Answer 1

The correct option is A 4 cm

Given,
$\text{Area}=10c{m}^2$
$\text{Height}=5cm$

$\because \text{Area}=\frac{1}{2}\times base\times height$
$\Rightarrow 10c{m}^2=\frac{1}{2}\times base\times 5cm$
$\Rightarrow base=\frac{20}{5}cm=4cm$
