A) \[225\,\,{{m}^{2}}\]
B) \[220\,\,{{m}^{2}}\]
C) \[330\,\,{{m}^{2}}\]
D) \[340\,\,{{m}^{2}}\]
Correct Answer: A
Solution :
Area of path \[=(x\times 2+x\times 2+x\times 2+x\times 2+4+4+4+4){{m}^{2}}\] \[=(2x+2x+2x+16)\,{{m}^{2}}\] \[=(8x+16x){{m}^{2}}=136\,\,{{m}^{2}}\] \[8x=120\,\,{{m}^{2}}\] \[x=15\,\,m\] \[{{x}^{2}}=225\,\,c{{m}^{2}}\]You need to login to perform this action.
