    Answer:

    1. d*1.49

    2. d/0.67

    Step-by-step explanation:

    One equation is already given in the statement which can give the result.

    Lets assume the area of painting = d = 10 sq inch

    Now following expressions will give the same answer.

    1. d+0.49d=10+(0.49*10)=14.9 sq inch

    2. Multiplying the percentage d, As the area increases by 49 % which means that D is multiplied by increased amount of 49%

    equation will be

    d*1.49=10*1.49=14.9sqinch

    3. Calculating the percentage increment = 1/1.49=0.67

    Now dividing this value with d will give the same area.

    =d/(1/1.49)=10/0.67=14.9 sq inch
