The length of the diagonal of a rectangular paddock is 61m and the length of one side is 60m. Find: |
(A) The width of the paddock |
(B) The length of the fencing needed to enclose the paddock |
A) 11m, 142m
B) 13m, 146m
C) 11m, 146m
D) 13m, 142m
Correct Answer: A
Solution :
(a) Width \[=\sqrt{{{61}^{2}}-{{60}^{2}}}\] \[=\sqrt{3721-3600}\] Fencing \[=2\times (1+b)=2\times \left( 60+11 \right)=142\]You need to login to perform this action.
