Question

the sides of a triangle are in the ratio of 2:3:4 and it's perimeter is 90 cm find area of the traingle​

Answer 1

Answer:

2x+3x+4x = 90

9x. = 90

x. = 10

putting values in diff forms of ratio

2x = 2×10 = 20

3x = 3×10. = 30

4x = 4×10. = 40

these are length of the sides ...

By using the eq for finding area with semi perimeter , you can find the area ...
