A) 155
B) 165
C) 150
D) 180
Correct Answer: B
Solution :
Let, b\[\to \] base and h\[\to \] height Area of triangle \[=\frac{1}{2}\times b\times h\,c{{m}^{2}}\] \[125=\frac{1}{2}\times b\times h\] or \[\frac{1}{2}bh=125\] ..?.(i) New base \[=120%\] of \[b=1.20\text{ }b\] New height \[=110%\] of \[h=1.10\text{ }h\] New area \[=\frac{1}{2}\times (1.20\times 1.10)\,bh\] \[=1.20\times 1.10\times 125=\]You need to login to perform this action.
