Its perimeter is cm. 90° b. Ichiro dilated triangle ABF with a scale factor of 2. 9. perimeter of ABC is 23, what is the perimeter of ABE? Q. Solution: b) Find the perimeter of rectangle BCEF. c) Find the perimeter of ABF. a. John builds a square with a side of 12 cm from some wire. Given that ∠ACF ≅ ∠ECFand m∠ABF = m∠EDF = 90, write a two-column proof to show that ABF ≅ EDF. Construct Arguments Write a two-column proof for the Angle Bisector Theorem. 28. 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. In the given figure, BCEF is a square and angle ABF and angle CDE are equilateral triangles. 34 cm.
