★ ∆ ABC is similar to ∆DEF
★ Area of triangle ABC = 64cm²
★ Area of triangle DEF = 121cm²
★ Side EF = 15.4 cm

★ Side BC

Since, ∆ ABC is similar to ∆DEF
[ Whenever two traingles are similar, the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides. ]

❍ <u>Putting the</u><u> values</u>, [Given by the question]
• Area of triangle ABC = 64cm²
• Area of triangle DEF = 121cm²
• Side EF = 15.4 cm

❍ <u>By solving we get,</u>






<u>Hence, BC = 11.2 cm.</u>

Answer:

Step-by-step explanation:
Step 1: Factor
g = a(H + n)
Step 2: Divide both sides by expression in parenthesis
g/(H + n) = a

Step-by-step explanation:
Standard form: -3x +5y= -1
Cylinder Volume = PI * radius^2 * height
Cylinder Volume = 3.14 * 2^2 * 9
Cylinder Volume = 113.04 cubic inches
