Answer:
The dimensions of AEHD are 3 inches and 3 inches
The perimeter of AEHD = 4 × 3 = 12 inches
Explanation:
* The figure is a rectangular prism
- It has two rectangular bases DCGH and ABFE with dimensions
4 inches and 3 inches
∵ DC = 4 inches and CG = 3 inches
∴ HG = 4 inches and DH = 3 inches
- It has two rectangular side faces ABCD and EFGH with
dimensions 4 inches and 3 inches
∵ DC = 4 inches and FG = 3 inches
∴ AB = EF = 4 inches and AD = EH = 3 inches
- It has two square side faces BCGF and ADHE with equal
dimensions 3 inches
∵ CG = 3 inches and FG = EH = 3 inches
∴ BC = 3 inches and BF = AE = 3 inches
∴ The dimensions of AEHD are 3 inches and 3 inches
∴ Its perimeter = 4 × 3 = 12 inches
