Answer:

The area is 72 cm².

Step-by-step explanation:

Since it is equivalent triangle

h = b

so,

b + b + b (since all sides are equal)= 36 cm

3b = 36 cm

or, b = 36/3

so, b = 12 cm

so

area of triangle = (1/2)×b×h

= (1/2)×12cm×12cm

= 6cm × 12cm

= 72 cm²

The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:

                     m= \frac{b-d}{a-c}.

Thus, the slope in A is m= \frac{12-2}{-4-(-10)}=\frac{10}{6}=\frac{5}{3}.

The slope in B is m= \frac{-4-10}{6-18}=\frac{-14}{-12}=\frac{7}{6}.

Now, to compare 7/6  to 5/3, we can write the second fraction as 10/6.


So, the slope in A is larger than the slope in B.

How do u work this out and what's the answer
I am Lyosha [343]
1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2
