The width of the rectangle is 25 cm How will the area of this rectangle change if a) its length is increased by 4 cm b) its length is reduced by 5 cm?
Formula: S = ab, substitute the values:
a.) 25 * (x + 4) = S
25x + 100 = S
25 * = S-100 – S will increase by 100 = 4/25
b.) 25 * (x-5) = S
25x-125 = S
25x = S + 125 – S will decrease by 125 = 5/25 = 1/5
