If price increase at a monthly rate of 1.3%, by what percentage do they increase in a year

If the price increase in the year
As know that there are 12 months in a year
1.013^(12)=1.1677
1.1677−1=0.1677
0.1677×100
=16.77% the price increase in a year

Hope it helps

Ucan draw that on a graph sheet and count the no. of units and apply the area formula of rectangle
