First, we need to find the base. To do so, we will need to use the Pythagorean Theorem on one of the smaller triangles to solve for its unknown side. Then, we can double the base of the one to find the base of the whole.
Pythagorean Theorem: a^2 + b^2 = c^2
(12)^2 + b^2 = (16)^2
144 + b^2 = 256
b^2 = 112
b = 
b = 
total base = 2 x
= 
Second, we can find the area. The formula for the area of a triangle is A = 1/2 x base x height.
A = 1/2 x
x 12
A =
x 12
A =
units^2
Third, we can find the perimeter. The perimeter is the sum of all of the exterior sides.
P = 16 + 16 +
P = 32 +
units
Hope this helps!! :)

Step-by-step explanation:
Answer:

Step-by-step explanation:
Given:

We need to find the ∠ IMN
Solution:
Now we know that;
∠ IMN = ∠ M ( Vertically opposite angles)
Substituting the values we get;

Also We know that;
∠ JIL = ∠ KIM ( Vertically opposite angles)
Substituting the values we get;

Now adding equation 1 and equation 2 we get

Dividing both side by 4 using division property of equality we get;

Now Substituting the value of 'x' in equation 2 we get;

Hence 
This is second term / first term = third term / second etc
so its 8 /32 = 1/4 answer
