Question

two equal side of an isosceles triangle are (3x-1) unit and (2x+2) unit the third side is 2x unit . find x and the perimeter of a triangle

Answer 1

since (3x-1) and (2x+2) are equal sides, then

3x-1=2x+2,

3x-2x=2+1,

x=3,

therefore

all the three sides will be

1st side=3×3-1=8 unit,

2nd side=2×3+2=8 unit,

3rd side=2×3=6 unit,


hence

perimeter of the triangle=8 unit + 8 unit + 6 unit=22 unit

Answer 2

Answer:

x = 3 ; the perimeter of triangle = 22

Step-by-step explanation:

since (3x-1) and (2x+2) are equal sides, then  

3x-1=2x+2,

3x-2x=2+1,

x=3,

∴ all three sides will be

1st side=3×3-1=8 unit,

2nd side=2×3+2=8 unit,

3rd side=2×3=6 unit,

hence

perimeter of the triangle=8 unit + 8 unit + 6 unit=22 unit
