Question

The length of the rectangle is four times it’s width. The rectangle has an area of 1024cm2. What is the width of the rectangle

Answer 1

Answer:

Length = 4 times width

Area = length * width

=(4w)w

=4w²

So 4w²=1024 cm² (given)

w²=1024/4=256

w=√(256 cm²)

=16 cm (reject negative value of square-root)
