Question

find perimeter and area of a right angle triangle pqr whose sides are 12 CM, 5 cm and 13 cm​

Answer 1

Answer:

It is a right angles

therefore,

area = 1/2 × b ×h. = 1/2 × 12 ×5 = 6×5 = 30cm^2

and,

perimeter = sum of all the three sides

= 12+5+13=30 cm...

Answer 2

Hypotenuse = 13

Base = 12 or 5

Height = 12 or 5  ( No change in values of area and perimeter )

Area = Base × Height × 1/2

        = 12 × 5 × 1/2

        = 30 cm²

Perimeter = 12 + 13 + 5

                 = 30 cm.
