Question

How do u solve problems like this ?

Answer 1

Step by step explanatio:

The first and second polygons are exactly the same, the only difference is that the second is bigger! If we look right the first polygon is 4 cm and the second is triple which means that we will have to triple the area of ​​the First polygon to discover the area of ​​the second polygon!

Resposta:

if the first polygon is 4 cm long and the second 12 cm means that the second polygon has three times the area of ​​the first polygon!

`(4 cm.3=12 cm)\\A-10 cm^(2).3=30 cm^(2)`

the second polygon has
`30 cm^(2)` of area

`A=30 cm^(2)`
