Question

find the area of a triangle two sides of which are 8cm and 11cm and the perimeter is 32cm ​

Answer 1

Answer:

Given:

. per metre equal to 32 CM

one side of triangle equal to 8 cm and

Other ,

Side of triangle equal to 11 cm

then first we find third side of triangle

p of triangle= sum of all sides

32 cm = 11+8+ third side

third side = 32- 19 = 13 cm

now,

. we find area ::- area of triangle = 1/2 X b X h

area = 1/2 X 8 X 13

. = 1 X 4 x 13

. = 52 cm^2
