Question

If two legs of a right triangle containing right angle are 4cm and 10cm. Find the area of triangle

Answer 1

Since both the given sides are perpendicular, therefore the height and base of the triangle is known i.e., height = 4cm & base = 10cm or vice-versa.

Area

$= \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 10 \times 4 \\ = 10 \times 2 = 20$

Hence, area off the given right-angled triangle is 20cm².

Answer 2

Step-by-step explanation:

Hieght is 4cm,

base is 10cm.

area is 1/2×10×4

20cm²
