Question

Find the area of a triangle two sides of which are 17cm and 10cm and the perimeter is 48cm

Answer 1

Step-by-step explanation:

Firstly find the third side so

17+10+x=48cm,48-27=21cm

Now area = 17×10×21

170×21

4570cm

Answer 2

Answer:

perimeter means sum of all sides

perimeter =48

then 17+10+x=48

27+x=48

x=48-27

x=21

then area of triangle=1/2 base ×height
