First, let’s find out how much 40% of the width is. Divide 25 cm by 100%, find out how much is 1%, then multiply by 40%.
25 cm ÷ 100% * 40% = 10 cm.
Add 40% to the width to get the length of the rectangle.
a = 25 cm + 10 cm = 35 cm.
Find the area of the rectangle. Multiply the width of the rectangle by the length.
S = 25 cm * 35 cm = 875 cm².
Answer: the area of the rectangle is 875 cm².
