Answer:
a=4
Step-by-step explanation:
100/a=25
100/25 =a
a=4
Lets cut this shape into rectangles and triangles.
The rectangles will be 7x3 and 3x4
So that is 21 sq rt and 12 sq ft.
Now the triangles.
One will be 2*3/2 and the other will be 4*3/2
So that is 3 sq ft and 6 sq ft.
In total the hole is 42 sq ft.
Step-by-step explanation:
Okay! Since these are similar figures we need to find the scale factor in order to answer this question.
We have a triangle with sides 7, 4, and 9. The longest side is 9. This corresponds with the longest side on the similar triangle, which is 36. So to find the scale factor we divide 36 by 9. The scale factor is 4.
Now to find the shortest side of the bigger triangle, we have to find the length of the shortest side on the smaller one which is 4. Since our scale factor is 4, we multiply 4 by 4 to get 16.
The length of the shortest side of the similar triangle is 16
