Question

sides of a triangle are in ratio 2:4:4. if the perimeter of the triangle is 120 cm find​

Answer 1

Answer:

24;48;48

Step-by-step explanation:

Let common number to be multiplied with ratios be x

x= 2x:4:5x

As the perimeter of Triangle is side + side + side,Then

$2x + 4x + 4x = 120$

Solve

$10x = 120 \\ x = 12$

Substitute x value in the ratios

$2x = 2 \times 12 = 24 \: cm \\ 4x = 4 \times 12 = 48 \: cm \\ 4x = 48 \: cm$

Answer 2

Answer:

you have not written what to find I am telling you sides in short

Step-by-step explanation:

let the common multiplier for sides be x therefore sides will be 2x 4x 4x. since 120 is perimeter.

120= 2x+ 4x +4x

120=10x

x=12

therefore sides are 2x=2×12=24

4x=4×12=48

4x=4×12=48

therefore sides of triangle are 24cm.48cm.and 48cm. respectively
