A) \[32\text{ }c{{m}^{2}}\]
B) \[~40\text{ }c{{m}^{2}}\]
C) \[~26\text{ }c{{m}^{2}}\]
D) \[28\text{ }c{{m}^{2}}\]
Correct Answer: A
Solution :
Given diagonal \[d=6cm.\] \[{{h}_{1}}=2.6\,cm\]and \[{{h}_{2}}=1.4\,cm.\] Area\[=\frac{1}{2}d({{h}_{1}}+{{h}_{2}})\] \[=\frac{1}{2}\times 16\times (2.6+1.4)=8\times 4=32\,c{{m}^{2}}\]You need to login to perform this action.
