A) 6m
B) 8m
C) 10 m
D) 12m
Correct Answer: C
Solution :
Perimeter of three squares are respectively \[12m,\text{ }20m,\]and 24m. \[\therefore \] Sides of three squares are respectively 3m, 5m and 6m. Combined area of three squares \[={{3}^{2}}+{{5}^{2}}+{{6}^{2}}\] \[=9+25+36=70\text{ }sq\text{ }m\] If length of the rectangle is x m, then \[x\times 7=70\] or \[x=10\,m\]You need to login to perform this action.
