Answer 1

Answer:

h = 40.5 m

A) 1 : 9

B) 1 : 3

C) 40.5 m

Step-by-step explanation:

Let the height of the larger triangle be h

Therefore,

$\frac{10}{90}= \frac{4.5}{h}\\\\\frac{1}{9}= \frac{4.5}{h}\\\\h = 9\times 4.5\\\\h = 40.5\:m$

A)

The ratio of the area of small triangle to the large triangle

$=\frac{10}{90}=\frac{1}{9}=1 : 9$

B)

The ratio of the side length of small triangle to the side length of large triangle

$=\sqrt{\frac{10}{90}} =\sqrt {\frac{1}{9}} =1 : 3$

C) The height of the larger triangle is 40.5 m
