If ΔABC∼ΔDEF such that AB=1.2 cm andDE=1.4 cm. Find the ratio of of areas of ΔABC and ΔDEF
If ΔABC∼ΔDEF such that AB = 1.2 cm and DE = 1.4 cm . Find the ratio of area of ΔABC and ΔDEF. [4 MARKS]
Trinagles ABC and DEF are similar. (i) If area (ΔABC)=16cm2,area(ΔDEF)=25cm2 and BC = 2.3 cm find EF. (ii) If area (ΔABC)=9cm2,area(ΔDEF)=64cm2 and DE=5.1 cm, find AB. (iii) If AC = 19 cm adn DF = 8 cm, find the ratio of the area of two triangles. (iv) If area (ΔABC)=36cm2, are (ΔDEF)=64cm2 and DE= 6.2 cm, find AB. (v) If AB = 1.2 cm and DE=1.4 cm, find the ratio of the areas of ΔABC and ΔDEF.
