Question

A rectangle has an area of 30.26 cm2. When both the length and width of the rectangle are increased by 1.80 cm, the area of the rectangle becomes 55.64 cm2. Calculate the length of the shorter of the two sides of the initial rectangle.

Answer #1

A rectangle has an area of 42.18 cm2. When both the length and
width of the rectangle are increased by 1.30 cm, the area of the
rectangle becomes 63.24 cm2. Calculate the length of the shorter of
the two sides of the initial rectangle.
The answer of 2.5 has been marked incorrect.

A rectangle has an area of 36.36 cm2. when both the length and
width of the rectangle are increased by 1.40cm, the area of the
rectangle becomes 57.50cm2. calculate the length of the tow sides
of the initial rectangle.

The length of a rectangle is increasing at a rate of 5 cm/s and
its width is increasing at a rate of 4 cm/s. When the length is 15
cm and the width is 6 cm, how fast is the area of the rectangle
increasing?

The length of a rectangle is increasing at a rate of 8 cm/s and
its width is increasing at a rate of 9 cm/s. When the length is 9
cm and the width is 5 cm, how fast is the area of the rectangle
increasing?

the length of a rectangle is 4 inches more than its width. the
area of the rectangle is equal to 5 inches more than 2 times the
perimeter. find the length and the width of the rectangle.
