B) AABF and ACDE are equilateral triangles ABF = 6 cm and BC = 8 cm.Find the area of the given figure Get the answers you need, now! 90° b. Therefore, BF = CE ( by CPCT) Problem 2: Given an ∆ABC whose perimeter is 13 cm and ∠ABC = ∠ACB and length of side BC equals 3 cm. 2. The width and length of a rectangle are two consecutive numbers. 21. 34 cm. Ichiro dilated triangle ABF with a scale factor of 2. Precisely explain the steps for dilating point F using the same center and a scale factor of 6. Problem 8. A rectangle is 16 m by 9 m. Find a side of the square whose area equals the area of the rectangle. Now, Perimeter = 2(l + b) = 2 (162 + 90) = 2(252) = 504 m. Therefore, cost for fencing the surrounding 504 m at the rate of ₹3.25 per metre = ₹(504 × 3.25) = ₹1638. 35 c Verbally opposite are ; a / r C) —3 S 75 70 les (Total for Question 3 is 4 marks) p 49308 A 0 420 350 750 . a.
