<em>429 cm²</em>

  • Step-by-step explanation:

<em>A(blue) =</em>

<em>= 2×6cm×10cm + 2×6cm×8cm + 8cm×10cm + (8cm×10cm - 5cm×4cm)</em>

<em>= 120cm² + 96cm² + 80cm² + 60cm²</em>

<em>= 356 cm²</em>

<em>A(green) =</em>

<em>= 4cm×5cm + 2×5cm×5cm/2 + 4cm×7cm</em>

<em>= 20cm² + 25cm² + 28cm²</em>

<em>= 73 cm²</em>

<em>A(total) =</em>

<em>= A(blue) + A(green)</em>

<em>= 356 cm² + 73 cm²</em>

<em>= 429 cm²</em>

numbers whose sum is 12

Sum =12         Product       Difference               Product- Difference  

11 +1                   11                    10                                1

500g of an item costs $12. Use the unitary method to find the equivalent cost of 320g.
zepelin [54]
A) 500g=$12 -> 100g=12:5 100g=$2,40
20g=2,40:5=$0,58
320g=3x2,40+0,58
320g=7,20+0,58
320g=7,78$

Set up a proportion and soive for<br> side TV (y):<br> ATUV-AXWV
slega [8]

As we Know that, ΔTUV\sim ΔXWV

So, for the given proportion TV(y) = 21.

What is Proportion?

A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)

What is Ratio?

The link between two or more things in terms of quantity, amount, or size.

Given that,

ΔTUV\sim ΔXWV

∠T = ∠X

∠U = ∠W

∠TUV = ∠XWV

So, TU/WX = TV/WV

10/10 = TV/21

1 = TV/21

TV = 21

So, for the given proportion the value for the side TV(y) = 21
