Question

Work this out please

Answer 1

Answer:

using the property of similarity of triangles ,we have:

(9/13.5) ^2= 34/ar(∆DEF)

or, 81× 4/729 = 34 / ar(∆DEF)

or, ar(∆DEF) = 34×729/ 324 = 76.5 m^2

Answer 2

Answer:

the answer is given below

Step-by-step explanation:

arABC/arDEF=BC²/EF²=9²/13.5²=34/arDEF

81/182.25=34/arDEF

arDEF=34×182.25/81=76.5cm²
