Answer:
F:53cm by 102cm
Step-by-step explanation:
The perimeter of a rectangle can be seen as 2l + 2w, with the length being l, and the width being d. If the ratio is 3:2, then 3+2= 5 parts would be the sum of the length and the width, This is half of the perimeter 2(l+w), so 510÷2 = 255. One part would be 255÷5=51.
If you put it into the ratio, effectively it is:
Length:Width
3×51:2×51
153 :102
Therefore the dimensions are 153cm by 102cm, which is F.
Answer:
600 x 60 = 36,000
50 x 50 = 2,500
1,000 x 3 = 3,000
70 x 80 = 5,600
100 x 300 = 30,000
20 x 40 = 800
90 x 90 = 8,100
9 x 900 = 8,100
500 x 300 = 150,000
1,000 x 5 = 5,000
125 - 100
770 - 800
364 - 400
923 - 900
755 - 800
