Question

the perimeter of triangle is 84cm and it's area 336 cm^2 CM. if one side measure 30cm find the other two side.

Answer 1

For area,

Area of triangle = 1/2 × b × h
336cm^2 = 1/2 × 30cm × h
336cm^2 = 15cm × h
336/15 = h
h = 22.4cm

For perimeter,

Perimeter = a + b + c
84cm = 22.4cm + 30cm + c
84cm = 52.4cm + c
84cm - 52.4cm = c
c = 31.6cm

The other two sides are 22.4cm and 31.6cm
