Answer:
Scalene triangle as there are no sides given.
or,
Measure it using a ruler and classify it based on the result.
Step-by-step explanation:
Scalene triangle = No sides are equal.
Isosceles triangle = 2 sides equal.
Equilateral triangle = All sides equal.
Right angled triangle = One angle is 90.
Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.
If, the triangle is for measure, measure it using a ruler and classify it based on the result.
Answer:
The dimensions are:
by 
Step-by-step explanation:
The area of the rectangle is given as

The factored form of this quadratic trinomial gives the dimensions of the rectangle.
We factor 3 first to obtain;

We split the middle term to get;

We factor within the parenthesis to get;

We factor further to get;

The dimensions are:
by 
Then the perimeter will be

4.5 is equal to k. This is the answer .
Answer:
b =21
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20^2 + b^2 = 29^1
400 + b^2 =841
Subtract 400 from each side
b^2 = 441
Take the square root of each side
sqrt(b^2) = sqrt(441)
b =21
