Find the area of the rectangle if it is 16 m long and 6 m wide. Find the perimeter of the rectangle if it is 9 cm long and 45 cm wide.
For a rectangle, opposite sides are equal, based on this, the formula for determining the area of such a figure corresponds to:
S = a * b.
Let’s find the area, provided that the length of the rectangle is 16 m and the width = 6 m:
S = 16 * 6 = 96 cm².
The perimeter is calculated using the formula:
P = 2a + 2b. If measurements are 9 cm and 45 cm:
P = 2 * 9 + 2 * 45 = 18 + 90 = 108 cm.
