Yes, because they are similar(or you can call congruent), proved by SAS or simply HL.

For that to happen, they must be similar. Maybe you've heard of Thales theorem?

So, let's see how the ratio of vertical to horizontal is:

3/7 (in the first triangle)
9/21 (in the second triangle)

Is 3/7=9/21? Yup. So that it is the second one.

The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.
Jobisdone [24]

Answer:

(B) 18 cm x 8 cm

Step-by-step explanation:

let the length be x,

then the width is \frac{1}{3}x + 2

2( \frac{1}{3}x + 2 + x ) = 52

\frac{1}{3}x + 2 + x  = 26

\frac{4}{3} x = 24

x = (24*3)/4

x = 18

then the length is 18 cm

and width is (1/3)*18 + 2 = 8

Therefore the dimensions are length:width = 18 cm : 8 cm

The solving of the fractions simply shows that the value of 1 2/3 + 3 1/2 is 5 1/6.

<h3>How to solve the fraction?</h3>

The first fraction give is:

= 1 2/3 + 3 1/2

= 1 4/6 + 3 3/6

= 4 7/6

= 4 + 1 1/6

= 5 1/6

Also 3/4 - 5/7 will be:

= 3/4 - 5/7

= 21/28 - 20/28

= 1/8

It should be noted that when solving fractions, it's important to have a common denominator.
