In un triangolo isoscele il lato obliquo misura 34 cm e la misura della base supera di 2 cm la misura dell'altezza. Determina il perimetro del triangolo dato.

What do we call the distance around a circle?

आकृति में \( A C=A C \) + \( A B=A D \) और \( \angle B A D \) \( \angle E A C \) है दबाईय के \( B C=D E \) है

8. If the ratio of the corresponding sides of two similar triangles is 35 , and the area of the smaller triangle is \( 27 \mathrm{~cm}^{2} \), then what is the area of the larger triangle? 9. If the area of two similar triangles are \( 144 \mathrm{~cm}^{2} \) and \( 720 \mathrm{~cm}^{2} \). Then find the ratio of the corresponding sides. 10. If Rectangle ABCD is similar to Rectangle EFGH, and \( \mathrm{AB}=10 \mathrm{~cm}, \mathrm{BC} \) \( =6 \mathrm{~cm} \) and \( \mathrm{FG}=18 \mathrm{~cm} \) then, what is a. The length of EF? b. The Area of Rectangle EFGH?

6. Two triangles are similar, if one side of the smaller triangle is half of the corresponding side of the larger triangle, and the perimeter of the larger triangle is 52 cm , then what is the perimeter of the smaller triangle?

Why is understanding surface area important in real-life applications?
