Answer: the perimeter of the larger triangle is 22 units
Step-by-step explanation:
The diagram of both triangles is shown in the attached photo. The isosceles triangles are triangle ABC and triangle DEF
Perimeter of triangle ABC = 11
For an isosceles triangle, the other two sides are equal. If one equal side is x, then the sum of the two equal sides is x+x = 2x
Perimeter of triangle = sum of the lengths of the 3 sides. Therefore,
11 = 5 + 2x
2x = 11-5 = 6
x = 6/2 = 3
The base of the similar triangle is 10. It means that it is 2 times the base of the smaller triangle. That means the scale factor is 2. Therefore,
If the perimeter of the small triangle is 11, the Perimeter of the larger triangle will be 2 × perimeter of the smaller triangle. This becomes
2 × 11 = 22 units.
It can also be determined by adding the length of each side
3×2 + 3×2 + 5×2 = 6+6+10 = 22 units
Answer$$$30
Step-by-step explanation:
Since she spent 2/5 of it, she has 3/5 left.
(3/5)x = 18
x = (5/3)(18) = 30
10 tripled equals 30 than 40 cut in half is 15 15+5=20 20=20
You could break down the shape and then get to the area but there is a better way.
The picture looks like a rectangle with a chunk pulled off it.
Let just imagine that it was a perfect rectangle.
Its dimensions would be 57 by 36 (20+16).
Perfect Rectangle Area = 57x36 = 2052
Now, let us find the area of the indent and subtract that from the previous area.
Indent Area = 16 x (57-15-15) = 16x27 = 432
Real Area = 2052 - 432 = 1620
answer = 1620
