The sides of one rectangle are 12 cm and 6.6 cm. The area of the 2nd rectangle

The sides of one rectangle are 12 cm and 6.6 cm. The area of the 2nd rectangle is 11 times less than the area of the 1st. Find the width of the 2nd rectangle if it is 8 cm long.

A rectangle is a rectangle with equal opposite sides and right angles.

Its area (numerical characteristic of a two-dimensional geometric figure) is calculated by the formula:

S = a * b.

1) Find this value for a rectangle whose dimensions are:

12 cm and 6.6 cm:

S = 12 * 6.6 = 79.2 cm².

2) We know that S of the other is 11 times less, let’s calculate it:

79.2: 11 = 7.2 cm².

3) Let us express the width of this figure if the length = 8 cm:

b = S: a = 7.2: 8 = 0.9 cm.
