Arectangle has a width w that is five units longer than its length l. which equation expresses the rectangle area

Area = L^2 + 5L units^2

Step-by-step explanation:

Length = L

Width = L + 5 Because it is 4 longer than the length.

Area = W * L

Area = L * (L + 5)

Area = L^2 + 5L units^2

You can test it by substituting number in:

If the length is 4 and the width is 9 (4 + 5)

4 * 9 = 36 units^2

4^2 + 5 * 4 = 16 + 20 = 36 units^2

total area = 39.6 square units

Step-by-step explanation:

determine the inside angle

360 / 5 = 72°

half of the triangle = 36°

given:

adj = 3.3

Ф = 36°

length of the opp of a small triangle is = adj. tan Ф

opp = 3.3 * tan 36 = 2.4

area of a triangle = 1/2 b * h   x  2 tringles

area =( 1/2 * 2.4 * 3.3  ) * 2

area = 7.92  multiplied by 5 equal shapes

total area = 7.92 * 5

total area = 39.6 square units
