Question

The two figures have a ratio of similarity of 3:4. If the area of the larger is 100 square units, what is the area of the smaller?

Answer 1

75 square units

Explanation:

set up a proportion first.

`(3)/(4) = (x)/(100)`

(x is on top because it asks for the smaller area, so it is on the same side of the 3)

after, cross multiply to find x

4x = 300

divide by 4

x= 75
