Question

the area of a right angle triangle is 40 cm square and its base is 10 cm find its altitude

Answer 1

Answer:

area of triangle = 1/2×base × Height

40= 1/2×10 × Height

40 = 10/2× Height

40=5 × height

40/5 = height

8 cm = height

Answer 2

Answer:

area of triangle = 40cm²

base = 10 cm

area of triangle =

$\frac{1}{2} \times base \times altitude \: \\ 40 = \frac{1}{2} \times 10 \times a \\ 40 = 5 \times a \\ \frac{40}{5} = a \\ a \: = 8cm$
