(i) Area of the part of the field, not covered by the roads. |
(ii) Cost of constructing the road at Rs.17 per\[{{m}^{2}}\]. |
A)
(i) (ii) \[3248\,{{m}^{2}}\] Rs.2890
B)
(i) (ii) \[10573\,{{m}^{2}}\] Rs.10659
C)
(i) (ii) \[16582\,{{m}^{2}}\] Rs.20480
D)
(i) (ii) \[10573\,{{m}^{2}}\] Rs.1250
Correct Answer: B
Solution :
(i) Area of path BSTV\[~=100\times 3=300\text{ }{{m}^{2}}\] Area of path MNDP \[=112\times 3=336\text{ }{{m}^{2}}\] \[\therefore \] Total area of two paths \[=(300+336)-\] Area of square HGFE \[=636-3\times 3=627\text{ }{{m}^{2}}\] \[\therefore \] Area of field not covered by roads = Total area of field - Area of two paths \[=(112\times 100)-627=10573\,{{m}^{2}}\] (ii) Cost of constructing \[1\text{ }{{m}^{2}}\]area = Rs. 17 \[\therefore \]Cost of constructing the roads \[=Rs.\,(17\times 627)=Rs.\,10659\]You need to login to perform this action.
