Question

fit the area and perimeter of a right triangle whose base is 12 cm height is 5 cm and hypotenuse is 13 cm

​

Answer 1

Answer:

area(Δ ABC) $= 30 \: {cm}^{2}$

perimeter (Δ ABC) $= 30 \: cm$

Step-by-step explanation:

area (ΔABC)

$= \frac{1}{2} \times base \times height$

$= \frac{1}{2} \times 12 \: cm \times 5 \: cm$

$= ( \frac{1}{2} \times 60) \: {cm}^{2}$

$= 30 \: {cm}^{2}$

perimeter (ΔABC)

$= sum \: of \: all \: 3 \: sides \: of \: the \: \triangleabc$

$= base + height + hypotenouse$

$= 12 \: cm + 5 \: cm + 13 \: cm$

$= (12 + 5 + 13) \: cm$

$= 30 \: cm$
