Triangles ABC and DEF are mathematically similar. CB 9 cm FE 13.5 cm The area of triangle ABC is 34 cm?. Calculate the area of triangle DEF.

9=100%

13,5=x

x=13,5×100/9

x=150%

it increased by 50%

so 34/100×150

area of DEF is 51 cm2

14

Step-by-step explanation:

Since we're given the conversion 24 cm for every 3 presents wrapped, we can divide our total amount of tape by this conversion, assuming a constant proportion.

Evren has 112 cm of tape. We can write the following proportion:

, where is the number of presents he can wrap with 112 cm.

Cross-multiplying, we have:
