Question

Find the area enclosed by each of (i) F E 디 20 m 1 1 10m G 20 m D AS 20 m B 20 m C cm.​

Answer 1

Answer:

Step-by-step explanation:

Given length l = 12 m breadth b = 9 m and height h = 8 m

Longest rod that can be placed in a room is nothing but its diagonal. Length of diagonal of a cuboid = √(l2 + b2 + h2) Length of longest rod = √(122 + 92 + 82) m = √(144 + 81 + 64) m = √289 m = 17 m Thus the length of the longest rod is 17 m
