Lets say we have a rectangle. if the ratio is 7:5, we can put the width as 7x, and the length as 5x (or vice versa, it doesn't really matter.) If the perimeter is solved by 2(h+w), we have 2(7x+5x)=96, or 2(7x)+2(5x)=96, which is C
By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
Find the ratio of the similar known sides:
1.34/2 = 0.67
The smaller triangle is 0.67 the size of the larger one.
Multiply the similar sides by the ratio:
DE = 4 x 0.67 = 2.68
FE = 3 x 0.67 = 2.01
Answer:
7 rows
Step-by-step explanation:
total 42 tiles. 6 columns mean, each column will have 6 tiles. so to have 42 tiles, 6*7 required
