Question

Area of triangle ABC similar to Triangle DEF. If AB=4cm and DE=5.6cm. If area of triangle ABC is equal to 25cm/square. Find area of triangle DEF
​

Answer 1

Answer:

25 sq.cm

Step-by-step explanation:

given that area of triangle ABC=DEF and ab=4cm and de=5.6 cm and area of ABC is 25sqcm

if area of ABC = def then it does not that what is the length of each side so area of def is 25sqcm

Answer 2

Step-by-step explanation:

$a(abc) \div a(def) = (ab)x(ab) \div (de) \times (de)$

by theorem of equal ratio

25/A(DEF)=4×4/5.6×5.6

25/A(DEF)=8/31.36

31.36×25=8×A(DEF)

784=8×A(DEF)

784/8=A(DEF)

98=A(DEF)

Area of Triangle (DEF) is 98 sq. cm
