The area of the trapezoid is 40 square units.
Whitepunk [10]

Answer:

5 units

Step-by-step explanation:

Image of the trapezoid is attached.

To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.

The formula for area of a trapezoid is:

A = (\frac{a + b}{2}) h

Here, a and b represents the bases of the trapezoid.

a = 6

b = 10

h which represents height is unknown.

A = 40

Substitute figures:

40 = (\frac{6 + 10}{2}) h

40 = (\frac{16}{2}) h

40 = 8 * h

Solve for h:

h = \frac{40}{8}

h = 5

The height of the trapezoid is 5 units

A square and a rectangle have equal areas.

Area of a square = Area of a rectangle

L² = H * W

If the dimensions of the rectangle are 15 units by 3 units,

L² = 15 * 3

L² = 45

Determine the length of the side of the square.

L = √45

L = 3√5
