Answer:

l = 2 1/2 ft

Step-by-step explanation:

Area is given by the formula

A = l*w

We know the area is 8 1/2

Changing this to an improper fraction 8 1/2 = (2*8 +1)/2 = 17/2

The width is 3 2/5 as an improper fraction = (5*3+2)/5 = 17/5

A = l*w

17/2 = l* 17/5

Multiply each side by 5/17

17/2 * 5/17 = l* 17/5 * 5/17

5/2 = l

2 1/2 = l

Answer:

l = 2.5 feet

Step-by-step explanation:

A = lb

8.5 = l * 3 2/5

8.5 = l * 3.4

l = 8.5 / 3.4

l = 2.5 feet (Always remember to put the units, otherwise you may not get points.)

What is the area of the composite figure?

Hello! :)

$\large\boxed{A = 32.5cm^{2}}$

We can use the following area to solve for the area of the trapezoid pictured:

$A = \frac{1}{2}(b_{1} + b_{2})h$

Where:

h = height

b1 = bottom base

b2 = top base

Plug in the given values:

$A = \frac{1}{2}(9 + 4)(5)$

Simplify:

$A = \frac{1}{2}(65)\\\\A = 32.5 cm^{2}$
