The areas of two similar triangles are 9cm2, and 49cm2. One of the sides of the first triangle is 2cm. What is the length of the

BlackZzzverrR [31]

Answer:

4 2/3 cm

Step-by-step explanation:

When we have area, it is the related to the scale factor by the scale factor squared

Area large/ area of small = 49/9

Take the square root

sqrt(49/9) = 7/3

The scale factor is 7/3 large to small

The small side is 2 cm

large 7 x cm

-------- = ------ = -----------

small 3 2 cm

Using cross products

7*2 = 3x

Divide by 3

14/3 = 3x/3

14/3 = the large side

4 2/3 cm
