Below is the solution:
60 - 44 = 16
16/60 = .2666
to round of .267
convert .267 to percentage by multiplying 100
.2667 x 100% = 26.67%
Answer:
Decrease in area would be 26.67%
Step-by-step explanation:
By decreasing each side of a rectangle by 1 unit area of the rectangle decreases from 60 square feet to 44 square feet.
So decrease in area = 60 - 44 = 16 square feet.
Percentage decrease in the area will be = \(\frac{\text{Decrease in area}}{\text{Area before decrease}}\times 100\)
= \(\frac{16}{60}\times 100\)
= \(\frac{160}{6}\)
= 26.67%
Decrease in area would be 26.67%
