If triangle RST and RZX are similar then the perimeter of triangle RZX is 150 units.

Given triangle RZX and RST are similar and RZ=28, RY=40,ZY=16 and SW=24.

In the similar triangles the ratio of sides are in proportion to the sides of other triangle.

The ratio of ZY to SW is 16:24 meaning it is 2:3. So all the sides of RST are 1.5 times as long as RZX.

RZ=28 so RS=28*1.5=42

RX=40 so RT=40*1.5=60

ZX=ZY+XY and since they are the of the same length , ZX=32 (ZY given)

Then ST=48

Perimeter of a triangle is the sum of sides of the triangle.

Perimeter of RST=RS+ST+RT

=42+60+48

=150

Hence the perimeter of triangle RST is 150 units.

Question is incorrect as it should be as under:

Given the following information, calculate the perimeter of triangle RST. Assume triangle RZX is similar to RST. RZ=28, RY=40, ZY=16 and SW=24.

Figure should also be given.

I don’t understand how to find the dimension,<br> Need help :c
slava [35]

Width = W

Length = 2 times the width plus 3 feet = 2W + 3

Area of triangle A = L * W

A = W (2W + 3)

20 = 2W^2 + 3W

2W^2 + 3W - 20 = 0

(W + 4) (2W - 5) = 0

W + 4 = 0; W = - 4 (width cannot be negative, excluded)

2W - 5 = 0

2W = 5

W = 2.5

L = 2W + 3 = 2(2.5) + 3 = 8

Answer:

Width = 2.5 feet and Length = 8 feet

Hope it helps.
