Answer:
total surface area = area of the two equilateral triangles + area of the 3 rectangles,
= 2(√3/4 a²) + 3( l x b )
= 2[√3/4 (3)²] + 3( 5 x 3 )
= 2 x 3.9 + 45
= 7.8 + 45
= 52.8 m²
Answer: 8 dolls.
Explanation: 13 - 9 = 4, 4 x 2 = 8.
Work the equation backwards... she has bought 9 extra dolls to add on the the half of her original amount. Without the extra 9 dolls (13 - 9), Jasmine has half of her original amount left (4) and so to find the original amount of dolls, think that if 4 is half the amount, what is 4 half of? 4 is half of 8 and so 8 is the original amounting dolls she had.

Hey there :)
We are given:
£ 1 = € 1.17
We need to find
£ 280 = ?
We can do this by ratio/fraction

or pounds : euros

We need to cross multiply to find the value of € when £280
? = 1.17 x 280
? = 327.6
£280 ≈ €327.6
