How many triangles can be constructed with the sides measuring 1m, 2m, and 2m.

Only one triangle can be constructed

Step-by-step explanation:

According to the question sides given are 1m, 2m and 2m

For the possibility of a triangle the sum of the two sides must be greater

than the third side

We have 1+2>2

⇒3>2

Also 2+2>1

⇒4>1

So  the possibility of a triangle is fulfilled

Only an isosceles triangle can be constructed

as two sides are equal

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
